Great Video! Detailed visual explanation... Thanks! I've had my Durango to several shops including dodge dealer and they all tell me they did smoke test but could not find leak. P0456 / and they charge me for diagnostics, clear code and tell me to see if comes back. BS! of course it comes back. I usually clear the code with my scanner to get through inspection. / I can only assume they're not checking anything. / I've lost faith, now I try to do my own repairs but sometimes it might be nice to rely on a mechanic!
Good info. My mother has a 2010 Dodge Journey with 2 codes (P0456 & P0457). Check engine light & gas cap is on. Got a gas cap from the dealer & cleared codes. Both check engine light & gas cap came back. I’m gonna have my mechanic do a smoke test. Thanks for the info. 👍
Thanks. What did you do? Also, my Code P456 just came ON again ((*: did come on **ten month ago, mechanic then,Cleared CODE, as PASSES MECHANIC’s EVAP & smoke testS….then. )). CHECKED :My, NEWER 2022,GAS CAP seems, is ok .. AND CODE456 does not appear to,go off yet. ..2015:JOURNEY 4 CYL.
Thanks for the video man! I replaced the leak detector, reset the cpu, and it popped up again. Just changed the purge valve. Gas cap looks good. If that damn code pops up again, guess I'll be replacing hoses and charcoal thingy
I just bought my 2014 Dodge ram 1500 with the hemi and I hadn't even got my license plate in the mail yet and started getting codes.. I called the dealer back and gave them crappy honest review online. Buyers beware 😢
i had this same problem for 4yrs and turned out to be seal at gas tank was bad causing my leak. Had whole gas tank replaced, has been good for a yr now and same code just popped back on.
I replaced the leak detector sensor that sends that code it’s $22 bucks on Amazon & that’s what my code reader said to do. I bet I saved my family $500
Good video. Very informative The components you show on Amazon !!! I don’t see any hoses for it underneath of my car It’s a dodge caravan 2017 My has broke need to replace but I don’t see any hose to connect to it! Do some come without the hose
You explained this so well. I have a 09 chevy suburban and it take fooreeeevvvveeeeerrrrr to put gas in it. It clicks every few dollars when trying to but gas in. Any ideas on how i can fix it?
Can find a dern purge valve.. On my 2003 dodge caravan the dang engine light with code po456 came on.. leak dtection pump is not like that white amazon module and nothing visible back by the tank.. Where is.any of this... only thing I can find is leak detection pump underneath drivers side by where the lower control arm is.
Question, I am getting a p0456 and can smell gas vapors when parked in the garage, but I only get the gas smell when I have a full tank...anything that is 3/4 tank or lower, no gas smell.
This is rare, however, you might have a tiny crack that is located higher than 3/4 on the tank. Consider making your own smoke machine? or partially dropping the tank and inspect?
Might mention this only seems to happen to me on my 12 jeep when it’s hot out. I don’t even do anything about it till it’s smog time as it does nothing to the vehicle.
I had a mechanic put my car on the computer last Sunday and everything was fine and now all of a sudden my check engine light is on with this code p0456 so can I still drive the car until I get it fixed? I brought the part (canister) that was recommended but waiting to get my mechanic put it on
This is the second time I've had this issue I bought a new gas cap a new charcoal leak detector pump and I bought a new solenoid I'm going to install all of them and see if this will fix it I hope so
I got the same code yesterday. I got a new gas cap today, how long does it take for the engine light to disappear if it was the cap? Im bringing it tomorrow to the mechanic but i just want to make sure im not jumping into mechanic when the code will eventually disappear if the driving cycle is not yet completed.
If fixed, the code should eventually clear, but it is usually cleared with an OBDII scan tool. 2010 and newer vehicles, the code will be permanent and need a drive cycle, but the light will go off.
Hey I just replaced the gas cap and pulled the battery for a few minutes. The check engine light went away and so did the trouble code except for a permanent one that my scanner cannot clear. What is a drive cycle and how long should it take? Should I even worry if the cel is not on anymore even though the code reader still shows the po456 permanent code?
@@AndSerts33 Each vehicle has a different drive cycle, which can be Googled to see what needs to be done. Usually, just driving around for 1-2 weeks will clear it, but if it needs cleared sooner, Google to see what the computer needs done.
@@HVAC_Mechanic thanks for responding so quickly! Ok, I have driven for a day or so. I will check it again sometime in a week. And probably Google it anyways. Thanks a lot. It’s been one thing after another ever since I passed 75,000 miles

Update: I made a full video on all the EVAP components and how to test them; here is a link. th-cam.com/video/C5s3Rx3wjD0/w-d-xo.html
Omg. This is a fantastic video. Very clear, to the point, easy to follow video. Great, clear visuals. Wish more people made videos the way you do.
This is the best video I’ve seen so far on what to look for when you get a P0456 code. Thanks!!!!

to say this is a fantastic video is an understatement , fight me!
Great video and thank you. These fixes also apply to the PO 1457 code.

@@oneofgodschildrensame here … such bs but besides the stupid evap leak shits a beast
I got my 2014 ram 3500 6.4 3 weeks ago and got a small evap leak code with a cracked heater return line hose before getting my license plate
How you reset the cpu? Sorry for the silly question but I have the same problem
i had this same problem for 4yrs and turned out to be seal at gas tank was bad causing my leak. Had whole gas tank replaced, has been good for a yr now and same code just popped back on.
Well done. Thank you for the video. I've got a little investigating to do.
Thanks-best video I’ve seen-simple and forward 😊
Thnak you for takng the time to do this.
Outstanding , thanks so much , I will try to fix it my self at my old age , if not if I take it to be fix , I won't feel Stupid .
I replaced the leak detector sensor that sends that code it’s $22 bucks on Amazon & that’s what my code reader said to do. I bet I saved my family $500
Did your car run rough before u changed it
Can you share the link?🙏🏽🙏🏽
Good video. Very informative
The components you show on Amazon !!!
I don’t see any hoses for it underneath of my car
It’s a dodge caravan 2017
My has broke need to replace but I don’t see any hose to connect to it!
Do some come without the hose
Good video. I would like to add the fuel pump might have a crack in it.
Can you use compressed are to find the leak or will the pressure srew something up?
I've never used compressed air in the EVAP system, but it is likely ok as long as the pressure is not too high.
You explained this so well. I have a 09 chevy suburban and it take fooreeeevvvveeeeerrrrr to put gas in it. It clicks every few dollars when trying to but gas in. Any ideas on how i can fix it?
Problems with the gas pump clicking off usually point to a vent valve issue.
Can find a dern purge valve..
On my 2003 dodge caravan the dang engine light with code po456 came on.. leak dtection pump is not like that white amazon module and nothing visible back by the tank..
Where is.any of this... only thing I can find is leak detection pump underneath drivers side by where the lower control arm is.
2007 Dodge ram hemi every two years leak. What could it be? Maybe something notorious
I have a 2016, 2500 ram 4.6L.. It keeps stalling (traffic lights & while in park), no engine light/codes.. Any ideas ?
Dodge needs to start making better products. Too many problematic parts on their vehicles.
It's called "planned obsolescence" that's been engineered to keep us making costly repairs and buying newer vehicles.
It's not that bad, after 8 years, I expect something to start messing up on my RT.
Tbh most of this stuff is pretty simple once you figure out that it's minor and learn a little bit about the car.
My truck is twenty years old and this code just came up. I can live with that. Best truck I've ever owned.
Ever owned a GM? 😂😂😂
Question, I am getting a p0456 and can smell gas vapors when parked in the garage, but I only get the gas smell when I have a full tank...anything that is 3/4 tank or lower, no gas smell.

Check the top of your gas tank (metal ring that holds fuel pump)
great summary, thank so much.

Well explained, very good video Thanks.
Thank you for the help

Were u able to drive it around with that problem back then?
I already changed new fuel cap. But fuel cap light still not gone.
Use a soap and water spray bottle. Good video
Thanks I have this very error and likely can fix meself!!!
Do you know if they're still using those charcoal cannister on newer models? Like 2022
Yes, charcoal canisters are still used.
Do you know of a good HONEST mechanic in the New Orleans area?
Thank you
Good video
THANKS for the video, super helpful!! 👍🏽
When to go do mine due to having a code replaced gas cap checked and I don't have one......
Great vid. Thank you.
very well done video!
great video, thanks
This is the second time I've had this issue I bought a new gas cap a new charcoal leak detector pump and I bought a new solenoid I'm going to install all of them and see if this will fix it I hope so
Did it fix it?
@@lonzosnags4995 still driving around..no CEL so far
Update, CEL came back on..will have to take it to a garage to get a specific reading on scanner..damn Mopars...
Great video
👍Great video thanks
I have the P0456 2 code. 2017 RAM 1500. What's the "2?"
Did you get an answer ?
I got the same code yesterday. I got a new gas cap today, how long does it take for the engine light to disappear if it was the cap? Im bringing it tomorrow to the mechanic but i just want to make sure im not jumping into mechanic when the code will eventually disappear if the driving cycle is not yet completed.
If fixed, the code should eventually clear, but it is usually cleared with an OBDII scan tool. 2010 and newer vehicles, the code will be permanent and need a drive cycle, but the light will go off.
@HVAC_Mechanic fir newer ones how long before it goes off?

I dont have a gas cap, I have a 2015 Dodge Durango.
The truck itself is a smoke machine .
Where can I find the leak detector on a 2018 dodge Durango
Autoparts store
Nice
Yup that stupid ESIM module caused mine
The computer or tipm?
@@Ali-wd1rz the actual thing that goes on the canister. Guess it’s a sensor of some kind and a very common cause of small leak codes on dodge vehicles
Hello
I have 2007 Dodge Dakota 4.7 with the same code .
Where's the government at now huh? This emissions garb was their idea..😂
Hook up smoke machine and see smoke rolling out of top of gas tank. Pulling it out :(
the only day i have off to go get my test done and the check engine light comes on and i get this code....😂 what kind of luck is this?🤦♂️
Awesome video, thank you
