How to Test and Repalce an EVAP Canister HD
ฝัง
- เผยแพร่เมื่อ 1 ต.ค. 2015
- Today we remove and test an EVAP charcoal canister. The canister is designed to hold hydrocarbons from the fuel system when the vehicle is not running. Under normal operation, the vapor is sent to the intake manifold when the engine is operating. This was performed on a 1997 Nissan Maxima. Check with your vehicle's repair manual for testing parameters.

I love how when folks do a show or a youtube video like this and when they spray the bolts it just pops off but when I do it I have to threaten the bolt and its family
😂😂😂😂
I think they leave it there for a while and come back

@UCExK5zIb68iMztT65gOLsAQ who the fuck are you?
this was me yesterday banging my knuckles against the concrete bc the pesky 10mm on my fbody wouldnt come off.... even after wd40... go figure but they broke..
the best video on youtube for this issue. I blew by mouth from the pipe and it was completely clogged. Tomorrow i'm going to buy a cheap used canister and i'll check it with this way. Thanks a lot
I got one of these as a code for my check engine light that came on, I’ve replace the gas cap and reset the light. A week later the check engine light came back on for 3 days and finally went away. I’m new to fixing my own car wanted to self learn and make this a goal to learn trouble shooting my vehicle. Thanks for the great video..!
Probably want to get a code reader first. Code readers aren't that expensive. If CEL came on for something else, messing with gas cap is already a waste of time/money.
For example I'm getting intermittent code for "oxygen bank1 sensor1 slow response"... Damn code comes & goes; I probably just need to clean the O2 sensor.
@@reallifeengineer7214evap codes are the worst, I have a 04 nissan titan and throwing the P1446 code, Scanned it and it said Vent Control Valve...Replaced it and light went away a month just for it to come back for the same thing. Replaced it again just for the same code to stay on
Good job on your Evap troubleshooting videos. They are very useful. I'm a new subscriber to your channel. Keep it up. Thanks.
+Andrew Young Thank you. Glad to help.
FYI you should also test from the tank side to the vent side with the purge capped, I'll seen these clog that way.
I love when you say “ very very excited” for replacing it :) same
Do it suppose to be alot of air come out or very little when u blow into the canister because mines have air but not to much
Would this cause problems starting up? I have a 98 dodge dakota v6 3.9L. Sometimes it'll start up find then other itll have problems starting & I have rev it up alot till it kinda warms up but has a rough idle.
Great information, 2011 Tacoma, code 456(evap small leak) smoke test shows smoke coming from tube that is attached the gas filler neck. Gas filler was covered and OEM gas cap remove. Attached tube was left uncovered during test and smoke was coming out. Technician wants to replace charcoal canister. Any advise. Thanks
Can you use CarbuCleaner or something like that to clean it up from inside?
I have a 2013 bmw 328i evap code came on. Had the fuel vent valve replaced. Code still comes on. I do have a muffler deleat. What else could it be?
Depending on the specific vehicle you could probably test it on the vehicle and save the removal and reassembly time if it's not bad.
Just tested mine yesterday with a Xtool D8.
How to test it?
Hi. I got an p0499 code and says evap pressure high. Tested the valve and it clicked. Could it be the canister? Car sometimes stalls. 2006 Chrysler 300c hemi. Thnx for the video.
The flow of air from one port to another just means the air can still pass thru. The carbon has to still be activated to do its job. Once the carbon is no longer activated you have to replace it.
And that's why a smoke test is best because it could be a good canister but it could have a crack at the seem 🤷
@@justinrivera2072 So... light a cigarettes, inhale, and blow into the tube? 😅
That's how I interpret smoke machine, I mean buying a smoker pump was a joke right?
Hi, I got a 2004 honda crv , with code p1457 , should I change the whole Vapor Canister , or just the Vapor Canister Vent Solenoid. thank you
What is the proper voltage, going back to the ecm?
i have 0443 code for my 2003 escape, I checked for voltage in the canister valve connector and theres no voltage.. check the 5amp fuse and it has power, any ideas what to do next?
Love the location of your charcoal canister! That job should be a piece of cake! 😂
This checks for clocks but what about small cracks causing vacuum leaks?
2009 Jeep Liberty Sport smells of gas when running, notice it almost every night backing into my carport where it smells stronger. Can smell a bit when car is off, EVAP canister or aftermarket gas cap? Also, P0455, P0456, and P0457 error codes, will check my EVAP purge valve Wednesday.
Now that was a good video short and sweet make me a subscribe thanks for sharing
Shouldn't you cover that hole also while your blowing to see if that canister is cracked ?
He didn’t check the vent valve correctly 🤦♂️ it might be stuck open. That’s why the air flowed right through. Isn’t it supposed to be closed when power is off to it?
@@rPlatt73 great point. This cannister is supposed to open and close at the right moment. It can certainly be stuck open and at other times be stuck closed. It needed further testing to verify.
@@rPlatt73yes, u r right.
Can I replace the hoses or is that something I should leave on? Thanks
I have a '99 Expedition w/ a 442 code. I smell fuel too. I don't know if the fuel smell comes from through the A/C vents or from the canister in the rear of the vehicle. Could a clogged canister cause any of my issues?
When I shift I can hear pressure release seems like it’s having trouble tho
Smell of gas when I fill up my camry. I fill it up with a gas can and funnel. Could it be the Crap canister?
Phenomenal video already subscribed I'm sure you'll show me other things that are helpful rock on brother
Hey Guys. Enjoyed the video. AI have a question. I have a 2005 Prius that is having problems filling up gas. I tried Your procedure to test if the vapor canister is the problem. I did have air come out the large port. Has some resistance but air does come out decent. Have You guys any experience with Prius not filling correctly? I mean I can only get 3 gallons of fuel in it. Thanks
Well the charcoal still needs to be able to absorb the fumes sufficiently as to not trigger a code. It's not just a matter of whether the canister is plugged.
Great video! :)
I have a 2007 Dodge caliber that sometimes smells in the area of the canister (driver's rear). Is this typical and does it need to be changed.
Thank you. I'd first check the gas cap; make sure it seals well. Any trouble when you add gasoline to the vehicle? In other words, the gas pump keeps shutting off? That's a typical sign of a worn canister. Scotty Kilmer has a good video about that issue. Just do a search on his page.
How many years do they usually last? Got mine changed under warranty in 2017
My 05 grand Cherokee isn’t throwing a code but when I try to fill the tank it stops 3/4 full and won’t take anymore. Could it be the canister you think?
Excelente..... gracias por compartir esta información
English this is America learn to speak it you learned how to count our money didn't you!!!
I have done nothing to the car and it came to me to be fixed. It's a 2000 Mercedes s 430. I'm thinking of changing the EVAP vent control valve but I was still like to know what causes that.. there is one video with the guy has the same problem with the same car but he hasn't found a fix either
Got a p2401 code. Already replaced the evap purge n80 valve and the gas cap so i guess this is the next thing ill check
2003 chrysler T and C lx model. I have code P 1684 and P 0456.
Help...
Thank you.
Is the charcoal pellets supposed to fall out of the canister, when u take it off,
Thank you now I understand why my gas was spitting back at least I feel more comfortable knowing it's not going to explode and what's happening thank you very much Anna
THANK YOU
I have a 2010 fusion se w 2.5l gas eng.under the grunk is the carbon canister(like you show) .is it defective now?and its rattling when i hit bumps.it started after hitting a huge pothole in buffalo ny this winter.ive been under the car and its secure,but if u bang lightly on it it rattles.all started frm the pothole
Bummer. I'm familiar with roads on the East Coast..brutal!
I have a 91 Honda Civic it has rough idle when I get to half a tank . Could this be causing the problem ? I already changed the fuel pump. Thanks
Ugh. I just replaced the control valve and filter and I'm still getting a PO446 control valve code. It cooouuld be the purge valve but I have a hunch that I'm going to have to jack up and tear apart that assembly I just put back together. 😢
what about the vent that you pinched off can you test that side of the canister? i am having problems filling my tank and i am wondering if it is not letting gas vent when i fill the tank. can you blow air in the tank and port and plug the smaller inlet shouldnt air come out of the vent port?
thank you
Yea, that often happens when the evap canister is clogged. Scotty Kilmer has a good video regarding the gas pump shutting off as you attempt to fill the tank. Just do a search on his page and you'll find it. Good luck.
The white can with 2 houses ?! What does it do ? What is it ? Thank you
Please help after resetting my 2000 Toyota Camry with a OBD 2 scanner i have driven my car over 520 miles...the check enginge sign never came back but all the monitors reported expect one
EVAP System Monitor its says INC (incomplete) ??? i know 520 miles too long a mechanic would not wait that long.yesterday i reset the car computer again this time by disconnecting negative battery terminal after driving for15 miles all the monitors reported expect EVAP system monitor i am supposed to take the state of illinois emission in January does it means it won't pass the emission test??? please suggest
what to do i really appreciate it thanks..
Hey there, I am having a hell of a time trying to figure out my 2001 5.3L Silverado issue. It has been throwing a p0440 code ever since I replaced the knock sensors a month ago. I checked the purge solenoid that is on top of the intake manifold and it is working properly, or I at least tried blowing into it and it was shut. I feel like its something i did when putting the intake back in that made the code pop up because I didnt have the code before, just the p0330 code for the knock sensor. Can you point me in the right direction at least, so i dont have to go get a smoke test to figure this out? Any help would be appreciated!
Oh, and I tried a new gas cap and that didnt fix it either...
So does it mean that the purge valve itself is bad?
2009 Hyundai sonata, how do I remove a fuel tank pressure sensor from fuel pump. how is it attached?
good to see if it holds a vacuum or air pressure no leaks from the seams.
If I blow into the big hole, nothing happens. It pressurizes.
If I block the small or medium hole and blow into the unblocked one, air comes out the big hole.
Is this normal operation?
Help please! I have a 2014 chevrolet equinox and I need to replace the vapor canister can you please tell me the steps involved or point me where I can find instructions on how to do it. Thank you
So then.. my charcoal canister is good??
Because I'm able to blow air from either side
I have a Vauxhall corsa and I can’t really blow through mine, is that a problem. Vauxhall Corsa D, built by Opel and GM
I have a fault code P1491 Vacuum Cut Valve Bypass Valve on a 2001 Nissan frontier 3.3L V6 could you help me out on where that's located?
Man! I have a 2008 impreza 2.5i. Today i noticed cuel dripping from a hole in the center of the right fuel tank plastic protector cover. At first I thought it could be coming from around the fuel canister or one of it's hoses. But I think the fuel tank protector cover is not covering that fuel canister (not likely the canister). But now I think it's either than my fuel tank is rusted through (salt from winters), or the fuel pump assy is leaking (cracked plastic connector ?). Changing the tank is 1800 USD, so I will definitely going to check my fuel pump assy first (I recon the whole unit is around 400$). The thing is I see dripping and smell gas only just after filling up or when the tank is near full. Today I noticed that reving the engine cause the leak to manifest, becoming more visible, whereas when I cut off the engine, I'm having a hard time seeing any dripping at all. That leads me to believe my leak is fuel pressure-realted (hence more likely a pump leak than a tank leak). Man I really hope it's the pump assy and not a rusted tank !!! BUT for diagnostic purposes, IN YOUR EXPERIENCE, Is the fuel canister covered by the right fuel tank plastic cover protector ???? If not, it's not the canister leaking for sure.
Are they known to get cracks in them
Ok will do thanx for the video .
Good luck!
Good to know...
If that's all there is to test, then it can be done "in situ" by removing the 2 smaller hoses and do a blow-through test... Yes ?
2014 Toyota FJ Mine is making humming noise hours after bieng turned off any feed back greatly appritiate.
Can the vent side go bad? This wouldn't test that aspect.
I have a p0446, thus far have replaced the purge and vent solenoid and gas cap. I checked my canister and air flows through it. Anything else I should check? I haven’t checked the fuel tank pressure sensor as it’s a new fuel pump and the pump came with a new sensor. I don’t have a scan tool to perform evap tests
What did it end up being & what symptoms did you have sluggish acceleration bog at 40?
My 2011 sonata 2.0t i barley drive with 59,500 garage kept has the po455 i changed gas cap, purge valve, Canister Vent Valve code came right back after 5 miles down the road what's next that i"m over looking?
Anyone know where it is on a 2011 e250 ford van thanks
I do not have a evap trouble code but when the car has been sitting after it's been driven gas is pouring out from the evap vent valve control. I need your help on what can be the cause? and do I have to replace the evap canister now because it is saturated with gas?
Did you recently do some work to the system and maybe mixed up the lines?
eighty6killa
CarsNToys no work has been done to it yet. but if gas is pouring from the vent control valve then that means the entire kind of store is full of gas right
How did u fix this problem.I just changed the fuel pump myself.Now I have fuel leaking from the vent valve too
I have a 2004 dodge ram 1500 5.7l hemi and everytime I fuel up it over flow even when it does not have any gas. What could be the issue.?
FROM CHICAGO EXELENT VIDEO. NOW CAN CHECK THE SWITCH CANISTER BY HOMS AND HOW PLEASE AND THANK YOU SO MUCH
will my evap system work without the water separator? just a temporary thing. Trying to get it legal. I'll replace it once I can get one in.
Depends. Some vehicles can get very finicky.
I have a 2007 Audi S4 4.2 V8. I got a purge valve flow error code. I changed the valve but the code came back after a few weeks. I removed the valve an noticed it was completely clogged with charcoal. Is it my canister that is leaking charcoal in the system? If so how would I know, and if I replace canister how do I clean the hoses leading to the purge valve? Thanks for any help on this!
You can check for leaks using a smoke machine.
Where is the evaporative fuel filter located?
thank you sir
Why take completely out? Couldn’t you disconnect hoses and blow with less trouble?
New subs here!
No fuel smell, P0455 . new LDP, canister flow valve, new canister vapor solenoid. new fuel cap, still this code. Shop did a smoke test, no signs of smoke. 2004 grand Cherokee.
Thank you
i got code po446 recently? i may have to rebuild my entire system not sure.
what happens is no air comes out? How does a blocked charcoal canister negatively effect one's EVAP system? What specific codes , if any, will be thrown if the charcoal canister is blocked?
P0456 small evap leak or p0455 gross leak.
my Cherokee has a ticking noise at the driver side rear.. would this be it?!
At all times or just when the vehicle is moving?
had gas pump clicking every few cents at pump..i have 05 explorer.check engine light codes was evap issue. i had purge valve replaced the evap codes cleared but still the same clicking problem at the pump.....where should i go next? HELP
That's indicative of a bad evap canister. Have you replaced the canister? Scotty Kilmer has an older video regarding the exact same problem you're having. Just search his channel.
thanks, I just went to a auto yards where you pull your own parts. took pictures of how everything is hooked up, pulled the part and replaced it on mine. still didn't take care of my problem. I've had the car for a month and replaced many parts, car still won't start. I'm about to push it in the river.
+Justin Gauger Sorry man. I know that feeling.
you tried switching the hoses?, could be the hoses if you already switched the canister & the valve
+Rick Ross sensor
So, which river is it in?
@@CarsNToys does gas come out
It’s sounds asinine but try using spray olive oil (for cooking). I used it once because i was in a pinch about 15 years ago and won’t use anything else now.
Thanks for your videos. Will you also do one on how to track down a small EVAP leak (ie. P1440)?
+EnragedPeach Actually I plan on doing 1440 very soon.
Yess!!
Before removing the canister ( disconnecting hoses/lines ) do you have to depressurize the fuel system first and if so, how? Is it as simple as removing the gas cap? Does the battery need also to be disconnected before you start removal of the canister?
For most vehicles you do not have to depressurize the fuel system. It's a good idea to disconnect the battery whenever you work on any vehicle. Here's how to depressurize the system (watch the first minute): th-cam.com/video/kSXQJja8AVI/w-d-xo.html
Thanks
Any time you remove a wire harness, shop manuals advise disconnecting the ground wire on the battery. If you are working near the gas tank, it's always a good idea in case of an electrical short. BOOM!!!
The mechanic that checked mine he left it on the vehicle all he did was remove a hose when he did a smoke test and you could see the white smoke coming out of the hose is this the correct way to check a cars charcoal canister?
I mean obviously if you were move a hose it's going to be coming out of the hose I don't know I'm a little confused about it. I didn't see any white smoke at all coming out of the canister or anything like that until he removed one hose
😒👍 Liquid Wrench Penetrating Oil, good stuff 😒👍
i have 2001 blazer p0440 code says its evap ststem and been stumped
Po455codigo Nissan frontier2007
Good info. Unfortunately, I already assumed that at 150k, the canister was plugged. Now that I find its working ok, guess I'll just return it to Amazon... Probly not the only time this has happened. Or should I just replace it anyway??? Or will in never go bad??? Its doing a slow fill at the gas tank...Just started with this tank of gas, perfectly normal fill on the previous tank.
Just watching this i get a po455 code everything i tried still comes up
Would a gas cap cause this problem
Joseph Marrs it can... Tho I've replaced mine.. The purge valve, vent solenoid, checked the evap canister, replaced all the vent lines when replacing the fuel pump a year ago... Time to get it smoked i guess. Part of being a happy gm truck owner... Hope your gas cap worked out.
Do you have one for a 2001 2.4 garnd am se ?
I'm afraid not.
2002 Tacoma v6 with gas smell after shutoff. Already replaced cap, no issues at pump. CEL codes P00440, P00441 & P00446. Tech thinks a bad vapor canister?
It's certainly a possibility. Another sign of a bad canister is constant shut off from a gas pump as you try to fill the tank with fuel.
Where is it on my 2014 Mustang v6?
do you need to relief gas pressure prior to removing any of those hoses?
Nope and in that case only if you turn it on for a while, if you do it off then you don't need it.
i have a honda accord 2014 model with the check engine sign on. scans revealed p2422; evaporative emission vent closed. please assist with comments
Thanks
How come you didn't show you removing the 2 'mounts' or taking off the opposite end of the hose you left connecconnected ??
I have a car puzzle mystery if any mechanics want to give me your input. There is a 2011 KIA Soul throwing a P0455 (large evap leak) code. We replaced the gas cap with an OEM KIA cap. I replaced the Canister Purge Valve solenoid. We ran smoke though it and saw no leaks anywhere. Took it to a Kia Dealership. They tested everything , bench tested the Evap canister , evap vent valve, gas cap , tested fuel pressure sensor and everything is checking out OK. But the P0455 code keeps coming back? The dealership said the Evap canister looks a little swollen but didn't show any signs of visible leakage. They said they could put a new Evap canister and evap canister filter on (which is 800 bucks) but cant guarantee that this will fix the problem. I was hoping that one of you on my friends list has gone through this or a mechanic might have a suggestion. Thanks
What happens if intake fuel port and purge port connections are interchanged??? This is serious question. 😐 Please answer.
Never got an answer 😩
Is your website not up and running anymore? I tried visiting it and it's just a generic domain page.
Not any more. I just created playlists here on TH-cam.
i am javing trouble pumping gas into my 2002 explorer when at the pump and trying to pump gas it keeps clicking off , would the canister be my issue
That's the most common cause. Also check the rubber lines.
That would be the valve he unpluged i think i gotta chamge mine but gonna check this first
Is this had to do with Engine Light on P0456?
No specific trouble code. I just did this as a how-to.
