Thank you for explaining how this charcoal fuel filter canister works. I saw mine hanging down and took it in for repair. Guy asked if I ran over something. Funny because I had just traveled over those raggedy New York highways... He also said it was hanging on by a zip tie, with. Hadn't noticed any fuel odor, so don't think it was cracked. The bracket holding it up was "cracked".
Thank you. Yes definitely that’s what’s going on. I over filled my tank trying to get as much gas in there as I could and ever since then my truck hesitates to take of. I am hoping to be able to fix this my self.
Thank you so much for explaining how this really simple system works. Causes so many problems and unfortunately, a lot of people get taken to the cleaners when they go to an auto mechanic. I like to do my own work and feel satisfied when I figure it out I hope I figure this out. Lol.
Thanks bud appreciate it I've narrowed down my assumption to the gas pump constantly shutting off when pumping to the charcoal cannister and the cannister purge valve
Oh wow I was thought that it was the way the fuel hole where you fill it up how it was at a angle My every time I pump gas I have to hold the handle otherwise it always clicks off well thank you
Thank you sir, I had several issues, one was the fuel pump (I ran it bone dry one day when I was doing work, didn't notice the low fuel light) then like you said, the pump handle kept tripping off) After filling the tank up, it wouldn't start. I'll be pulling the evap canister today!
Evap systems send unburnt gas back into your engine so you're making your car less fuel efficient bypassing it. Also the fumes are bad for you. Basically not fixing it is very stupid (& so is Florida's lack of emissions standards imo)
Your channel should have 2 million subscribers, by the way Sir if at all possible may I request a topic regarding pre ignition or pre detonation that causes that light pinging sound during acceleration and how to fix it? Thanks Sir
Thank you for your awesome explaining video. My car before drive around 45 mls/ gallon ( Prius 2007) and now only 25-27 miles/ gallon. it shows the code P0455 and it doesn’t smell gas at all. I’ve already check the purge valve but it still work properly. Do you think it is from charcoal canister problem ? Or anything relate to that problem ? Thank you 👍👍👍🙏🙏🙏🙏
I have a 1998 3.3L Nissan Pathfinder. 175,000 miles. Great condition. Stock. My tank gets alarmingly pressurized when driven a couple hundred miles. I don't have any codes. My Nissan gas cap visually inspects clean and good. Does not leak. I even disconnected all hoses on the EVAP system and cracked the gas cap. No codes were made either. How can that be? I drove it dozens of miles to test. To see if the missing stopped or codes would appear. No codes, except random misfire. Every now and then, but the motor is obviously missing mildly to badly all the time. It gets worse for a while when I refuel. For a few dozen miles. When this system started doing this, I started getting a random misfire code at the same time. These may be unrelated. Not sure. I have verified purge valve works, hoses are clear now. One was dirty about 2" clogged at the canister for the purge line. It looked like charcoal dust. All other hoses clear. Any ideas? I was going to remove the plug from the cannister ambient vent valve and see what that did. It should toss a code right? And make the valve open, from my understanding? I don't want the tank to pressurize like that again. It will spew and hiss for about 6 minutes when cap is removed. I've never seen a vehicle do it this badly before. Thanks!
2005 toyota corolla Ce, no fault code,brand new 02 sensor upstream and downstream but the upstream is not ready or incomplete. No check engine light on.

@@day1fishing603 well I have the same issue but I changed the gas cap two years ago and its oem. I called the dealership but they said I should have them inspect it because it can be the filler neck
I had the same problem on a 2006 Ford. It was the fuel tank purge valve. It was stuck closed. When the engine was turned off the valve was supposed to open so the fumes could travel to the charcoal canister and be stored so they could be burned off when the engine is started and running. When it was stuck closed the fumes created when filling the tank had nowhere to go. The gas pump would shut off. The only way to get gas into the tank was you had to hold the handle on the nozzle. Also when the tank reached full fuel would be forced up and out of the filler neck. I changed the valve sensor, and that cured the problem.
I have some other symptoms. My gas gauge is stuck at 3/4 (it goes to zero when I turn off the car). I have bad smell of gas inside. It's worse when the car is off. What could it be, is it sending unit or EVAP system, or both? My fuel pump or fuel regulator are not cracked at top.
Can the cannister be bad but not shut gas off constantly when pumping? I see that a lot of people have replaced a lot of parts and spent a ton to do it but keep having the same problems. I have seen videos showing people using a cover on the capless gas tank and stoping the codes and the problems starting after gassing up. Can it be as simple as covering the flapper on the capless gas system neck? Very worried about going to our dealership as they have been very clear about wanting me to trade my car so they can have it for their used inventory. My car is low mileage and in great condition and one they don't make anymore so I do not feel comfortable going to the dealer for service right now. I love my car and no way I'm trading it, but this actually only started after going in for them to take a tack out of my tire (which did not damage) and an oil change. They also scraped brake calipers to "check brakes" and had some decent debris and dirt in the wheel wells. I understand debris can cause the flappers in the capless gas inlet. No problems prior but we drove out with rough engine and then a few weeks later stalled at gas up first time. Wondering if the debris could have gotten into the gas fill area? Seems odd to have this only after going in for service but not before. Trust level gone but I don't know any good mechanics. We have 1 car and I need it not to stall on gas up. Also saw a video where someone said the seals on the flappers of the capless gas opening can erode and need to be maintained. They showed spraying compressed air to clean flapper area and then wd 40 or liquid silicone and using the funnel that comes with Ford Fusion to push in and out of gas opening 30 times to clean and recondition the seals. I have a p0496 small leak that I read can be from debris in a gas tank opening flapper seal. Have you heard of this and do you have any thoughts on it. Can doing that funnel thing cause any damage? Thanks.
@@lightningfisher8177 I know. I have the worst feeling about going there bc Ford wants my car and have been very obvious about it. All they have to do is tell me they cannot fix it or it is unsafe to drive once they have it and I am stuck without my car that I love. I have seen reviews of this. But I don't know where else to take it and where there are good mechanics here in Central FL. I have heard there is a shortage of good mechanics and those who are good are being bid on so lots of repair places are doing low bids for their workers. Also I am still inside of warranty and don't want to void it by having service done and having Ford tell me bc of that my warranty is gone. Right now we have the gas neck dirt inlet cover and some people say it works to stop this stalling at gas up and the leak situation but I don't want to make it worse by using it without knowing everything about it first. I need someone with automotive knowledge to tell me what I should do as I want my working car back! It's a small leak and if just at the gas cap area I don't want to have every part replaced one at a time at the dealer and then the car to be kept by them. Sorry for the essay.
Question? Please. At the back one hose get disconnected and a clear liquid leak from this hose ( the evap line). I reconnected with a new ring that was full rusted. But i wonder that liquid ,what is this? and should i purge the liquid ? Is it suppose to be dry and empty ( gas is no liquid!).
Hi i have a hyundai accent 2007 and im having problems starting the car after i put gasolina, i put new the gas cap, vapor canister purge valve, which is next to the throttle, the other valve that is on the valve cover and also the oone located next to the canister and still having problems, let me know what can it be, it's driving me crazy. Thanks and great video
Does it cause a sudden drop in MPG? I can hear an intermittent sort of noise like a momentary vacuum leak. Particularly loud first start up or at low speed in a parking lot for example. 03, S10, 4.3 ltr.
My check engine light and VSC tracking light were flashing two weeks back on my 2010 Corolla LE. At that time I had just filled my gas tank and noticed a strong gas vapor as I drove out of the gas station. Didn't think of it much as I thought it's some other car. Later on, I got the check engine lights and VSC tacking lights. My mechanic diagnosed the code as P0456 Evap Emission Control System Leak detected (very small leak). So, they replaced the gas cap with an OEM and reset the codes. So far the lights have not come on. Went to the gas station yesterday and filled up my tank. After I started driving, I smelled a strong gas vapor/fume. I pulled over and then opened the trunk after turning off the car and could smell the gas vapors/fumes in there. Is this a bad charchoal canister or vent?
If you want to smoke test your EVAP lines, do you do it from the service port? And do you have to pull any other hose off for venting so the smoke can get down the line?
great video ,, i have 08 mountaineer v8 ,, code P0135,P0141,P0155,P0161 and P0443 came up all at once , i noticed that when putting fuel in the car and the car in ON then it shut off while fueling ,,, can this be a canister problem ? ..
Question for you. I only get the check engine light when I park on the fourth floor of were I work. P0442. I have changed the purge valve and the vent valve too. If I drive on level road it never comes on. Only comes on when it’s parked on elevated fourth floor. You have anything for me. Haha
How would you know if it's the vent solenoid valve going bad and not the charcoal canister going bad, is there a test for that? I replaced the purge valve and the gas cap and the codes came back, so it could be the vent solenoid valve or the charcoal canister or both, how would I know?
Hello, I’ve taken my 02 GMC sierra 1500 5.3L truck to different auto parts stores to check why my engine light keeps going on and off. They all gave me a P0443 code. They say it’s the canister purge valve. I have replaced it 3 times with new ones but, the engine light still goes on and off. What else do you recommend me to do? 🤔
What if you have a very small evap leak ? I’ve had small issues with my 2005 mustang gt for years. I replaced the fuel cap and the evap purge valve with oem motorcraft parts but still once a year I get the same code and clear it and it’s fine for awhile.
Dear sir, I can fill up the car up but,about 1 hour it stalls out and I have to take a can of extra gas with me after I add the gasoline, it starts up just fine after it gets to the fuel lines can you help me with this question ❓
Hi very informative video. I have a 2016 Corolla with strong fuel smell coming from AC vents first 1-2 min after being started in morning, then clear normal air and no engine codes. Any idea of what could be my issue?
I have a Toyota with a p0446, is that the purge valve by the charcoal canister? Sometimes when I start the car there is a gas smell but then it goes away.
My s550 mustang 3.7 canister is likely bad due to age of 8 years old. And I been getting rich conditions and some lean conditions and the car would shake after getting gas as well.
How about no CEL, no DTCs, no driving symptoms, but have a yellow light on the code reader and a flashing EVA that won’t reset. I’ve inspected the canister and all of the hose connections for leaks and removed and cleaned the foam filter inside the canister.
Hello. I have a 06 ram 1500 and recently i can smell raw gas near the drivers side rear wheel well after i drive it home and park it. I looked under it and there were no leaks that i could see. I tried to look on top of the gas tank as best i could. I didnt see any obvious leaks but really could not see well. I looked at the evap csnister ans hoses. All looked ok and i didnt detect any gas odor around the canister. I could see the fuel pump on top of the tank and therd was another device up there but i dont know what it is. No check engine light. Any ideas.
I have a 2012 Honda Civic LX and I'm getting a p420 code and an EVAP code. I'd like to buy just a cheap cat to get me by because I plan on buying a new car after 2 years. Do you think if I buy an aftermarket cheap eBay cat it'll pass emissions as long as I fix the EVAP code as well
@@Top5AutoRepairs Thanks. I've been trying to locate the problem in my blazer. When I fuel up the check engine light will turn off for a while but will come back on.
I have all those symptoms on my 2007 Honda pilot EXL but I’m also getting a check fuel cap but I already replaced it can the charcoal canister be the problem for that too
Hello, i have a little bit of fuel smell when i start-up the car, now when i put my car to obd diagnostic and i go under "charcoal valve" the valve opens and closes every second, should valve work like that or not?
I’m replacing mine because of the small and large leak detected ..question should I reset code or just let the computer reset itself after I replace it 2007 Jeep Grand Cherokee 5.7
I know that my Evap canister is not functioning, but I am noticing white smoke also when the car is ON and not moving. Is this related to the evap system issues? Also, please advise me where can I find a brand NEW replacement of my canister for infinity q50.
Every now and then after I’ve been driving and shut the car off and restart it, I get a gurgling pulsating sound coming from the passenger side, and if I pop the hood and squeeze the line going from the purge solenoid to the intake, the gurgling stops until I unpinch it, no codes no CEL, I do have crappy gas mileage and smell super rich gas fumes, starts fine runs fine, it just started doing this
I have every signal of a bad vapor canister like the gas pump stopping unless I pull the nozzle all the way out to the tip of the fuel tube and pump slow, Car reeks of super rich gas fumes for a good two minutes after you start the car inside and out, bad gas mileage, engine twitches But doesn’t affect the RPMs, And also, after I finally do fill up the tank after several tries, I get a chugging sound coming through the passenger side dash, and if I squeeze the vacuum line between the purge solenoid and the intake it stops, take a little while to settle down when I come to a stoplight, but I have zero codes and no CEL
@@majicdude88 I can also hear when I’m getting low on gas. My fuel pump starts grumbling louder. It never used to do that before only in the last month or two.
@@majicdude88 also I don’t know if it means anything but every time I turn my key on my pump primes, even if I shut the key off and turn it back on it primes again and if I turn the key off right away and turn it back on right away the pump primes again and so on like somethings not holding pressure, car starts and runs fine
@@stopher1971yeah the pump primes every time you start the car, or seconds prior anyways. So doing what you described could flood the motor on many cars.
Good info, I have a 06 titan with check engine on? I changed code sensor p0057 and I changed purge valve p0047 that code never came back. But 02 sensor one did ? Wierd because shop fixed that 02 sensor what can be the cause should I take truck back to them ??
All good, except: "In California, 2000 and newer model year vehicles will need all emission monitors in READY or COMPLETE status with the exception of the EVAP monitor. An incomplete evaporative monitor will not cause a smog check failure. The Bureau of Automotive Repairs has reduced the number of allowable incomplete OBD II readiness monitors for both the new BAR-OIS smog inspection system and the BAR-97 smog inspections systems, however the EVAP monitor is the one monitor that is still allowed to remain Not Ready and will not cause a smog test failure." However: In the real world, Smog Inspection businesses are highly monitored by the State, and if they don't "fail" a certain percentage of vehicles, the State will send in "test" vehicles to try and bust the Smog station for illegally passing vehicles that have "something" wrong, which could be as simple as a disconnected hose that would automatically "fail" a "visual" inspection as no repairs or modifications are allowed. Here's another "trick" to passing smog: When you go in, ask the Smog station to "check the readiness monitors to be sure the car is ready to be smogged." They will 100% check the monitors anyway, usually before they even do a visual they will hook up their scan tool and see if there are any codes or Check Engine Lights, an automatic fail. But, if you ask them to check for "readiness" first, then they cannot fail you if your car is not ready, because you asked them to check BEFORE they started any test procedures. If you don't ask, and they test to see the readiness monitors are not ready, then it's an automatic fail. Again, if they were to do this simple courtesy for every customer, then a large percentage of fails would not be sent away with an automatic fail. Then, the percentage of passes would be abnormally high, and that smog station would get flagged by California's Bureau of Automotive Repairs (BAR) and they'd start sending in test vehicles to bust the station. Often, the Smog station will tell people to 'drive 50 miles' or some such advice to 'clear' the monitors. However, there are many 'drive cycle procedures' that one might follow that could clear and ready the system in under ten or twenty miles. I have gone to smog's that the Evap was not clear, and have driven over 200 miles and it still doesn't clear, despite doing very rigid adherence to a drive-cycle procedure. The Evap can literally go 500 miles and still not clear. Some unethical stations will tell you that the car 'failed' if the Evap is not ready. But, it doesn't have to be for certain years and types of cars. BTW: I've used Catyclean with some success, including helping my MPG increase as well as helping pass smog. Having sold about 100 used cars in the last five years, I"ve had plenty of smogs. Usually, you want to go in when the car is nice and hot, having driven about 20 miles or so before the smog, and tuned up the car and be sure you hook up everything as it should be. For example, leaving a vacuum hose off the airbox will be an automatic visual fail. For all that smog tech knows, you are from the BAR and trying to bust them for simply helping out someone by saying, "Hey, looks like you left your vacuum hose off." When I was a kid, back in the 1970's, it was common to see cars going down the road leaving so much smog that you could not see across the street after they drove by. So, it is an important thing to help with the air quality. But, three are definitely some smog places that lie to people and say that the car is not ready when all it is is the Evap, and they tell the person to go out and drive, which is not at all guaranteed to clear an evap. I've personally put over 1,000 miles on a car and the Evap doesn't clear.
You do not start with the charcoal filter . There is an evap solenoid by the tank and another vapor sensor by the engine .on chevys. Changing the charcoal tank would be last on the list of things to.check lol but 1 of the steps none the less . P o449 code does not just mean charcoal cannister
I just recently purchased a brand new 2023 Rav4 and OVERFILLED my gas tank twice out of ignorance obviously. That's how recent I've purchased the vehicle. I'm nuts with this thing and with doing things RIGHT. Do you think ANY damage could have been done to the system with just TWO times?
I have a 98 pathfinder and my car is experiencing some symptoms where I’ll step on the gas and it’ll shift into 1st and 2nd but it hit the rev limiter shifting into 3rd. I’ve replaced the evap solenoid due to one of the hoses having carbon deposit built it up in it. Should I then replace the vent solenoid after emptying out my charcoal canister?
Hello Auto repairs, i am using the same Lexus RX300, 1999 model engine 1MZFE. the accident was made by swap/connecting the Vacuum Surge Tank pipe to the water outlet there just below it. The system was filled with water until the water comes out at The Charcoal Canister through the Air Drain Horse. We have tried to remove the water by sucking and blowing through the pipes and even put the new service kit since we found some plugs socked in water. but still the car wont start but cranks. what advice can you give sir
It seems like water made its way into the combustion chamber. Remove all spark plugs, remove water from the combustion chamber and next conduct a compression test. Hopefully the engine didn't hydrolock and caused mechanical damage.
I have following codes: P0441, P0442, P0446, P0455. Gas fuel tank cap was replaced with new OEM cap. Mechanic at Toyota dealership says I need to replace fuel filler neck assembly. Watched several videos for these codes and couldn’t fond any mention of that part in relation to evap codes… Am I being fooled?
It does not have to be the canister it's self that cause gas to smell I just had this problem and it was my vent solenoid that's located on the canister .
This is great. I have the P0455 issue on my 2007 Tahoe. Will replace it soon. Would this also cause my acceleration to have a problem? When it's warm outside, the truck seems to bog down and refuse to accelerate. I'll have it floored and there'll be little to no acceleration. It doesn't feel like it's flooded, just won't accelerate. If I back off the throttle a little and accelerate slowly it will then accelerate "ok". Not a major issue, but concerning when trying to accelerate at a stop light or trying to merge onto a highway. Fortunately it's not the transmission - it's not revving high, it's just not acceleration. (EDIT) Forgot to mention it seems to stick at about 1500 RPM when it's doing this.
@@krasmurdok it might also be your throttle position sensor or the (accelerator) pedal position sensor...and I'd lean toward the pedal position sensor. Pretty easy fix. What's happening in my case (I just learned) is mine is going into "limp mode" and limiting my throttle revs (I'm maxed at 1500 rpm) and keeping me at 2nd or 3rd gear. Should take about 20 minutes max to replace it. I just ordered the part.
thanks for the video, question: read code 4456 (Evap small leak), after test smoke, smoke is coming from the pipe that is attached the gas tube. could that me charcoal canister. thanks
Evap vent valve for the canister stays open with engine off so you have to either use a scanner to command it shut or manually remove the vent valve line and block it off by pinching the line or putting something in there to block it then do your smoke test, good luck.
Thanks for the video. I have been trying to tell people what there problem might be. But no one wants to listen. After I show them this video maybe they might listen to. Oh yeah most or should I say all of them what I think there car problems are I tell them what I think and they always seem to reply that I don't know what I am talking about. So why ask for my opinion in the first place? Oh yeah 👍 great advice.
Thank you for explaining how this charcoal fuel filter canister works. I saw mine hanging down and took it in for repair. Guy asked if I ran over something.

Wwwww2
Thank you for taking the time to do all your videos. Two of them have helped me out. Didn’t have to spend big money at a machine shop.
Even me it helped abt the high pressure pump.

I believe that I did the same thing
Can also be the purge valve
When the pump clicks off do not pump more gas into the tank
Thank you. You saved me money from taking it to the dealership to have it checked out 🙌
How did he help u ?

That's awesome dude. Thanks for sharing so quickly and to the point. Mine looks like crap and the hoses are old so it might be time.

What if I bypass the charcoal canister😮. I live in Florida where we don't have emmision testing nor do we need to deal with safety stickers 😅
😀
You're wasting money not using an EVAP system.
Evap systems send unburnt gas back into your engine so you're making your car less fuel efficient bypassing it. Also the fumes are bad for you. Basically not fixing it is very stupid (& so is Florida's lack of emissions standards imo)
Thanks also there is foul smell coming out of the exhaust
How should we go about replacing the hoses? What size hoses should we use? Where to buy?
Did you ever find one? Thanks

Seems odd to have this only after going in for service but not before. Trust level gone but I don't know any good mechanics. We have 1 car and I need it not to stall on gas up. Also saw a video where someone said the seals on the flappers of the capless gas opening can erode and need to be maintained. They showed spraying compressed air to clean flapper area and then wd 40 or liquid silicone and using the funnel that comes with Ford Fusion to push in and out of gas opening 30 times to clean and recondition the seals. I have a p0496 small leak that I read can be from debris in a gas tank opening flapper seal. Have you heard of this and do you have any thoughts on it. Can doing that funnel thing cause any damage? Thanks.
dont go to stealerships!!!!!!!!!!
@@lightningfisher8177 I know. I have the worst feeling about going there bc Ford wants my car and have been very obvious about it. All they have to do is tell me they cannot fix it or it is unsafe to drive once they have it and I am stuck without my car that I love. I have seen reviews of this. But I don't know where else to take it and where there are good mechanics here in Central FL. I have heard there is a shortage of good mechanics and those who are good are being bid on so lots of repair places are doing low bids for their workers. Also I am still inside of warranty and don't want to void it by having service done and having Ford tell me bc of that my warranty is gone. Right now we have the gas neck dirt inlet cover and some people say it works to stop this stalling at gas up and the leak situation but I don't want to make it worse by using it without knowing everything about it first. I need someone with automotive knowledge to tell me what I should do as I want my working car back! It's a small leak and if just at the gas cap area I don't want to have every part replaced one at a time at the dealer and then the car to be kept by them. Sorry for the essay.
Question? Please. At the back one hose get disconnected and a clear liquid leak from this hose ( the evap line). I reconnected with a new ring that was full rusted. But i wonder that liquid ,what is this? and should i purge the liquid ? Is it suppose to be dry and empty ( gas is no liquid!).
Learning is always useful! Thanks
Is the charcoal filter similar to a catalytic converter in diesel engines?
I have a 2000 Dodge Durango 5.9 engine it runs about 20 or 30 minutes there's no oil on the stick but when it cools off it's full of
Hi i have a hyundai accent 2007 and im having problems starting the car after i put gasolina, i put new the gas cap, vapor canister purge valve, which is next to the throttle, the other valve that is on the valve cover and also the oone located next to the canister and still having problems, let me know what can it be, it's driving me crazy. Thanks and great video
Was it your fuel filter
I have same issue did you fix it and what was it?
Does it cause a sudden drop in MPG? I can hear an intermittent sort of noise like a momentary vacuum leak. Particularly loud first start up or at low speed in a parking lot for example. 03, S10, 4.3 ltr.
Hello. It will affect gas mileage.
@@Top5AutoRepairs At least now I know where to look.
My check engine light and VSC tracking light were flashing two weeks back on my 2010 Corolla LE. At that time I had just filled my gas tank and noticed a strong gas vapor as I drove out of the gas station. Didn't think of it much as I thought it's some other car. Later on, I got the check engine lights and VSC tacking lights. My mechanic diagnosed the code as P0456 Evap Emission Control System Leak detected (very small leak). So, they replaced the gas cap with an OEM and reset the codes. So far the lights have not come on. Went to the gas station yesterday and filled up my tank. After I started driving, I smelled a strong gas vapor/fume. I pulled over and then opened the trunk after turning off the car and could smell the gas vapors/fumes in there. Is this a bad charchoal canister or vent?
Thank you. This makes so much sense.
If you want to smoke test your EVAP lines, do you do it from the service port? And do you have to pull any other hose off for venting so the smoke can get down the line?
great video ,, i have 08 mountaineer v8 ,, code P0135,P0141,P0155,P0161 and P0443 came up all at once , i noticed that when putting fuel in the car and the car in ON then it shut off while fueling ,,, can this be a canister problem ? ..
Question for you. I only get the check engine light when I park on the fourth floor of were I work. P0442. I have changed the purge valve and the vent valve too. If I drive on level road it never comes on. Only comes on when it’s parked on elevated fourth floor. You have anything for me. Haha
How would you know if it's the vent solenoid valve going bad and not the charcoal canister going bad, is there a test for that? I replaced the purge valve and the gas cap and the codes came back, so it could be the vent solenoid valve or the charcoal canister or both, how would I know?
Are you getting a p1450 like me?
My car is giving off a strong propane gas smell when running. Would has vapors change their smell after interacting with the charcoal?
Hello, I’ve taken my 02 GMC sierra 1500 5.3L truck to different auto parts stores to check why my engine light keeps going on and off. They all gave me a P0443 code. They say it’s the canister purge valve. I have replaced it 3 times with new ones but, the engine light still goes on and off. What else do you recommend me to do? 🤔
Did you figure out ?
What happen if purge valve not openning? How many minutes to open the purge valve?
What if you have a very small evap leak ? I’ve had small issues with my 2005 mustang gt for years. I replaced the fuel cap and the evap purge valve with oem motorcraft parts but still once a year I get the same code and clear it and it’s fine for awhile.
Oh yeah I have that issue too. Filling up with gas sometimes is very hard. Getting past 8 gallons is very difficult sometimes
I have a code p1450 and the engine shuts off a few times only after i get gas. Would this be a purge valve issue?
What if the code is P0457 on a 2006 Dodge Dakota.
It shows gas cap but I have replace it a couple of times...
I have a 05 Eddie bauer with a p0453 code what will fix that?
Dear sir, I can fill up the car up but,about 1 hour it stalls out and I have to take a can of extra gas with me after I add the gasoline, it starts up just fine after it gets to the fuel lines can you help me with this question ❓
Hi very informative video. I have a 2016 Corolla with strong fuel smell coming from AC vents first 1-2 min after being started in morning, then clear normal air and no engine codes. Any idea of what could be my issue?
A leaking heater core, you are smelling coolant
@@kellismith4329 Hi, thanks for the comment I think that is a very possible problem.
I have a Toyota with a p0446, is that the purge valve by the charcoal canister? Sometimes when I start the car there is a gas smell but then it goes away.
Im getting pieces of charcoal particles going into evap purge solenoid
My s550 mustang 3.7 canister is likely bad due to age of 8 years old. And I been getting rich conditions and some lean conditions and the car would shake after getting gas as well.
Very helpful and easy to understand. Thank you for making this video!
How about no CEL, no DTCs, no driving symptoms, but have a yellow light on the code reader and a flashing EVA that won’t reset. I’ve inspected the canister and all of the hose connections for leaks and removed and cleaned the foam filter inside the canister.
Hello. I have a 06 ram 1500 and recently i can smell raw gas near the drivers side rear wheel well after i drive it home and park it. I looked under it and there were no leaks that i could see. I tried to look on top of the gas tank as best i could. I didnt see any obvious leaks but really could not see well. I looked at the evap csnister ans hoses. All looked ok and i didnt detect any gas odor around the canister. I could see the fuel pump on top of the tank and therd was another device up there but i dont know what it is. No check engine light. Any ideas.
I wondering if a hard to fill up gas tank could be the the leak detect leak pump or switch? and not the canister I have a P4149 switch pressure
I have a 2012 Honda Civic LX and I'm getting a p420 code and an EVAP code. I'd like to buy just a cheap cat to get me by because I plan on buying a new car after 2 years. Do you think if I buy an aftermarket cheap eBay cat it'll pass emissions as long as I fix the EVAP code as well
Great video! I think I will finally get my problem solved. Thanks for your insight.
Will a damaged canister cause a lean condition on both banks?
Yes
@@Top5AutoRepairs Thanks. I've been trying to locate the problem in my blazer. When I fuel up the check engine light will turn off for a while but will come back on.
I have all those symptoms on my 2007 Honda pilot EXL but I’m also getting a check fuel cap but I already replaced it can the charcoal canister be the problem for that too
Hello, i have a little bit of fuel smell when i start-up the car, now when i put my car to obd diagnostic and i go under "charcoal valve" the valve opens and closes every second, should valve work like that or not?

Do I need to program my car if I need to change my carbon canisters
I know that my Evap canister is not functioning, but I am noticing white smoke also when the car is ON and not moving. Is this related to the evap system issues? Also, please advise me where can I find a brand NEW replacement of my canister for infinity q50.
Every now and then after I’ve been driving and shut the car off and restart it, I get a gurgling pulsating sound coming from the passenger side, and if I pop the hood and squeeze the line going from the purge solenoid to the intake, the gurgling stops until I unpinch it, no codes no CEL, I do have crappy gas mileage and smell super rich gas fumes, starts fine runs fine, it just started doing this
If you don’t mind there’s a video here on YT titled “Infiniti G35 “weird noise” and thats exactly the sound I have
Where is my charcoal canister located on my 96 ford ranger?
I have every signal of a bad vapor canister like the gas pump stopping unless I pull the nozzle all the way out to the tip of the fuel tube and pump slow, Car reeks of super rich gas fumes for a good two minutes after you start the car inside and out, bad gas mileage, engine twitches But doesn’t affect the RPMs, And also, after I finally do fill up the tank after several tries, I get a chugging sound coming through the passenger side dash, and if I squeeze the vacuum line between the purge solenoid and the intake it stops, take a little while to settle down when I come to a stoplight, but I have zero codes and no CEL
That’s your vent valve being stuck closed, not your charcoal canister
@@majicdude88 the vent valve on the canister? I’ll replace it, looks like a 10 minute job on my car g35 coupe

Tanks for all that info😊
All good, except: "In California, 2000 and newer model year vehicles will need all emission monitors in READY or COMPLETE status with the exception of the EVAP monitor. An incomplete evaporative monitor will not cause a smog check failure. The Bureau of Automotive Repairs has reduced the number of allowable incomplete OBD II readiness monitors for both the new BAR-OIS smog inspection system and the BAR-97 smog inspections systems, however the EVAP monitor is the one monitor that is still allowed to remain Not Ready and will not cause a smog test failure." However: In the real world, Smog Inspection businesses are highly monitored by the State, and if they don't "fail" a certain percentage of vehicles, the State will send in "test" vehicles to try and bust the Smog station for illegally passing vehicles that have "something" wrong, which could be as simple as a disconnected hose that would automatically "fail" a "visual" inspection as no repairs or modifications are allowed. Here's another "trick" to passing smog: When you go in, ask the Smog station to "check the readiness monitors to be sure the car is ready to be smogged." They will 100% check the monitors anyway, usually before they even do a visual they will hook up their scan tool and see if there are any codes or Check Engine Lights, an automatic fail.
But, if you ask them to check for "readiness" first, then they cannot fail you if your car is not ready, because you asked them to check BEFORE they started any test procedures. If you don't ask, and they test to see the readiness monitors are not ready, then it's an automatic fail. Again, if they were to do this simple courtesy for every customer, then a large percentage of fails would not be sent away with an automatic fail. Then, the percentage of passes would be abnormally high, and that smog station would get flagged by California's Bureau of Automotive Repairs (BAR) and they'd start sending in test vehicles to bust the station.
Often, the Smog station will tell people to 'drive 50 miles' or some such advice to 'clear' the monitors. However, there are many 'drive cycle procedures' that one might follow that could clear and ready the system in under ten or twenty miles. I have gone to smog's that the Evap was not clear, and have driven over 200 miles and it still doesn't clear, despite doing very rigid adherence to a drive-cycle procedure. The Evap can literally go 500 miles and still not clear. Some unethical stations will tell you that the car 'failed' if the Evap is not ready. But, it doesn't have to be for certain years and types of cars.
BTW: I've used Catyclean with some success, including helping my MPG increase as well as helping pass smog. Having sold about 100 used cars in the last five years, I"ve had plenty of smogs. Usually, you want to go in when the car is nice and hot, having driven about 20 miles or so before the smog, and tuned up the car and be sure you hook up everything as it should be. For example, leaving a vacuum hose off the airbox will be an automatic visual fail. For all that smog tech knows, you are from the BAR and trying to bust them for simply helping out someone by saying, "Hey, looks like you left your vacuum hose off."
When I was a kid, back in the 1970's, it was common to see cars going down the road leaving so much smog that you could not see across the street after they drove by. So, it is an important thing to help with the air quality. But, three are definitely some smog places that lie to people and say that the car is not ready when all it is is the Evap, and they tell the person to go out and drive, which is not at all guaranteed to clear an evap. I've personally put over 1,000 miles on a car and the Evap doesn't clear.
Twenty thirteen escalade changed purge valve vent sylanoid And vapor charcoal canister and I still can't pump gas without it keep stopping
Thanks pal--- very enlightening!
Glad it was helpful!
Mine shows a small evap leak. Tried changing the canister, not it. Very hard to find small leak.
You do not start with the charcoal filter . There is an evap solenoid by the tank and another vapor sensor by the engine .on chevys. Changing the charcoal tank would be last on the list of things to.check lol but 1 of the steps none the less . P o449 code does not just mean charcoal cannister
I just recently purchased a brand new 2023 Rav4 and OVERFILLED my gas tank twice out of ignorance obviously. That's how recent I've purchased the vehicle.
I'm nuts with this thing and with doing things RIGHT. Do you think ANY damage could have been done to the system with just TWO times?
No but stop overfilling the tank.
I have a 98 pathfinder and my car is experiencing some symptoms where I’ll step on the gas and it’ll shift into 1st and 2nd but it hit the rev limiter shifting into 3rd. I’ve replaced the evap solenoid due to one of the hoses having carbon deposit built it up in it. Should I then replace the vent solenoid after emptying out my charcoal canister?
Great video
Can this cause my tank to leak fuel
My check engine is in but for 02 sensor
Hello Auto repairs, i am using the same Lexus RX300, 1999 model engine 1MZFE. the accident was made by swap/connecting the Vacuum Surge Tank pipe to the water outlet there just below it. The system was filled with water until the water comes out at The Charcoal Canister through the Air Drain Horse. We have tried to remove the water by sucking and blowing through the pipes and even put the new service kit since we found some plugs socked in water. but still the car wont start but cranks. what advice can you give sir
It seems like water made its way into the combustion chamber. Remove all spark plugs, remove water from the combustion chamber and next conduct a compression test. Hopefully the engine didn't hydrolock and caused mechanical damage.
I have following codes: P0441, P0442, P0446, P0455. Gas fuel tank cap was replaced with new OEM cap.
Mechanic at Toyota dealership says I need to replace fuel filler neck assembly. Watched several videos for these codes and couldn’t fond any mention of that part in relation to evap codes… Am I being fooled?
I have the same codes I haven’t changed mine yet I’m still studying before I change it
Any updates on how yall fix this? I'm in the same 🚢
Does a damaged canister affect acceleration? I recently changed my Gas pump and filter and it’s still failing to accelerate when I press the gas pedal
Fuel pressure regulator.
Do you have to empty fuel tank in order to replace charcoal canister?
Nope. Just disconnect the pipes, unbolt the old one, refit new one. Easy as.😊
Your awesome bro.
It does not have to be the canister it's self that cause gas to smell I just had this problem and it was my vent solenoid that's located on the canister .
My 2010 grand cherokee gives me a purge valve can and i switched it already and it keeps giving me the same code
Does the engine shake too?
P1447 I couldn’t find the issue on 98 maxima , I need help please
Good explanation
This is great. I have the P0455 issue on my 2007 Tahoe. Will replace it soon. Would this also cause my acceleration to have a problem? When it's warm outside, the truck seems to bog down and refuse to accelerate. I'll have it floored and there'll be little to no acceleration. It doesn't feel like it's flooded, just won't accelerate. If I back off the throttle a little and accelerate slowly it will then accelerate "ok". Not a major issue, but concerning when trying to accelerate at a stop light or trying to merge onto a highway.
Fortunately it's not the transmission - it's not revving high, it's just not acceleration. (EDIT) Forgot to mention it seems to stick at about 1500 RPM when it's doing this.
How did that turn out because my 2016 tucson is doing the exact same thing
@@krasmurdokI haven’t gotten around to it yet. Other priorities have gotten in the way 😂
@@m1cajah understood
@@krasmurdok it might also be your throttle position sensor or the (accelerator) pedal position sensor...and I'd lean toward the pedal position sensor. Pretty easy fix. What's happening in my case (I just learned) is mine is going into "limp mode" and limiting my throttle revs (I'm maxed at 1500 rpm) and keeping me at 2nd or 3rd gear. Should take about 20 minutes max to replace it. I just ordered the part.
Wheres your shop? Thanks
thanks for the video, question: read code 4456 (Evap small leak), after test smoke, smoke is coming from the pipe that is attached the gas tube. could that me charcoal canister. thanks
Evap vent valve for the canister stays open with engine off so you have to either use a scanner to command it shut or manually remove the vent valve line and block it off by pinching the line or putting something in there to block it then do your smoke test, good luck.
Can you tell me where I can see a diagram so I can better understand. Thanks
