2010 Jeep Wrangler Evap Leak - How to Find, How to Fix, & How to Confirm Repair - DTC P0456 P0455

[@Zmsf01Zmsf01]

About to try this soon on my 2009. I already replaced tank once, 11,000 miles ago. I don't want to drop the tank completely. I appreciate this. Thank you. Wish me luck.

[@DantheFixitMan]

Best of luck to you! I hope it all works out ok!

[@michellejackson7752]

I was receiving the P0456 Code as well. I replaced all the usual suspects, the gas cap, the vapor canister and found your video. I crawled under the jeep and found the same crack in the valve at the top of the tank. I mixed some epoxy and coated the valve and voila! Its fixed! You nailed it! Nice job!

[@michellejackson7752]

Another symptom I've noticed that has resolved since I addressed the issue is that when I would fill up my tank, the fuel pump would often shut off unexpectedly, regardless of the position of the pump handle. However, since I repaired the crack with epoxy, this problem has disappeared.

@@michellejackson7752yea mine does that a lot! Going to give this a try soon

[@vdog4799]

​@@michellejackson7752I heared that! Thats a bummer when its bad, it can take a long time to fill up.

You mentioned that your smoke machine was ghetto and cheap or whatever. On the contrary it's actually amazing. You just saved me $100. I'm having the same issue. I've just changed my head gasket lower manifold gasket and put new headers on and there's still some minor issues going on and I definitely need to do the smoke test. Thank you for your video

My wife's 2011 had this problem recently, $280 at local Jeep dealer to diagnose, said it was the EVAP pump unit and they quoted many $$$ to fix it, plus about $80 for part. Got it online for $17 and replaced it, no help. Had another Jeep person come look at it and he found this nipple broken off. He would fix it or replace tank for $800 to $1500. He said repair would be much less, but we did not get an exact amount, so after watching this and a couple other videos, I 3D printed a tube out of TPU which fixed it temporarily... found out the next day my wife messaged me "The engine light is off!" Then I bought some 4.5mm OD brass tubing with 1mm walls on Amazon once I knew the exact size, cut it to about 1.5" and epoxied it into both halves of the nipple with JB Plastic Bonder epoxy... worked great, solid as a rock! The best part about this is that it doesn't have the slit down the side of the tube. Thanks for the video!

[@leer670]

Dude I wished you lived closer to me I need help with mine what part did you replace I have done the gas cap the ESIM under the driver side and fixed the gas tank. Send me the part # or name so I can look it up and replace that part PLEASE TY

Had this same issue on a customers wrangler and it only threw a P0440. Smoked it and sure enough cracked nipple. Engineers weren’t thinking when they designed this thing…great video!

[@peterzinia3767]

That sure is a nice code reader. Good for getting info worthless for any real diag help. I got one like it. My 01 XJ has been throwing the 0455 for a week. Guess I better get out there & handle it.

[@WyitoG]

Check engine light has been on for months. Found this video and as soon as I reached for this line it snapped right off. Headed to the hardware store for the pin and epoxy right now!

[@gregsmith9650]

Good video, but you found the problem in the first 3 minutes. You just wanted to try out the homemade smoke machine, which is actually pretty cool

[@jpphd5685]

2010 Jeep JK. Changed my gas cap and that helped. A few times I did not turn it until it clicked after pumping gas which gave me a check engine light. I got rid of my permanent code by disconnecting my battery and tying the cables together to get rid of all residual power in the systems. Then I took out my TIPM, removed all fuses and relays and cleaned all contacts on the TIPM and fuse leads. After that I sprayed contact cleaner into each contact on the TIPM. Then I put dielectrical grease on the TIPM connectors when putting it all back together.

[@jerryjones28]

I have a 2013 Jeep Wrangler, the local Jeep Dealership wanted estimate cost of $1100 dollars to correct this. I reset the dash engine lite by disconnecting the battery & the lite is off. I started using plus gas & help me out a lot.

[@ari88881]

This fix probably makes it more durable. I had an EVAP system leak on my 2013 with 70k miles, same on my 2016 with only 35k miles. Going to give it a shot this weekend T.Y.

[@destructo6745]

Is that a 1967 Cougar in your garage!? Nice. Great jeep video, too!

[@DantheFixitMan]

Yes, it is! Thx!

[@Chefbriank]

THX I KNOW WHERE MY LEAK IS GETTING DRIVE PINS TODAY AND EPOXY OF COURSE! MY WHITE PLASTIC NUB WAS COMPLETELY BROKEN OFF

[@BRTbike-fz5fn]

My 2008 was a combination of gas cap and ESIM. Hot dry Southern NM and AZ desert just dry rots everything. Cap O ring was hard as a rock and almost flat. ESIM was cracked where it was plastic welded together and the seals inside were hard too.

[@drewbush6535]

How do you know if the canister valve is open or closed when blowing smoke through it

[@frankciongoli6449]

Awesome video. Helped me a lot!!😊

[@ogxchrisx1339]

Great job and explanations man. What do you think about the use of JB weld puddy instead of epoxy?

[@DantheFixitMan]

No problem, I think JB weld would work fine too. Thanks for watching! -Dan

[@varovaro3555]

I think should be recall on this Issue.. However , What is the length of the roll pin ? It’s 5/32 x ? I did smoke my jk with cigar and it turned out same leak-as yours . Thanks for your video , was helpful.

[@peterzinia3767]

You know that it takes 3 to 5 driving cycles to br certain that the repair worked. It could come back. They usually do. Jeep is synonymous to evap leaks.

[@DantheFixitMan]

Yes, the evap repair worked and there are no dtc's present and the evap monitor is still showing as complete. I only have this update because the owner just brought it back to me this week because it failed the California Smog Check. Not because of the Evap issue, but because that o2 sensor I/M readiness monitor still will not complete, even after a few months and hundreds of miles driving it. I have read several of the jeep forums on this and apparently a lot of people have the exact same issue. They say that the fix is to have the computer 're-flashed' by the dealership, or 'just keep driving it until it completes.' The owner took it to the dealer, but the service writer said that it 'might not work.' I believe there is a TSB for this issue as well. I recommended that they go back to the Dealership with the TSB info in hand, or maybe try a different dealership. If anyone out there knows about this, or has had this same issue, please let me know if you got it figured out. Thanks! -Dan

[@Gunderblinx]

My 2018 wrangler has an evap leak. Wont allow me to use remote start because of it. Thanks cali.

[@vdog4799]

Thank you for the video. That gives me a great help to ferret this out👍 At least an idea of how to start.

[@erikgour3475]

Of course its the middle of winter in New England and this shit is going on with my jeep. Thanks for the 411 though.

[@justcaldwell]

Great video! Thank you!

[@DantheFixitMan]

Thank you, glad you liked it! Take care, -Dan

[@ManWithaPlan1658]

Perfectly done! Many thanks!!

[@w9jim]

Want to come over to my house and do that all over again? 😀

[@DantheFixitMan]

Haha, thanks for the invite! It’s really not that bad once you find the leak. Best of luck to you!

[@LuisGonzalez-rv9zb]

Thank you for the video.

[@maisyray]

Boom! Fixed-it!

[@kaedoe204]

Great video

[@e6bnfo]

Great video. What area of California if you are taking customers? Any more info on how to make the smoke machine?

[@DantheFixitMan]

Here is the video that I followed for making the smoke machine. kzbin.info/www/bejne/fXLUeaSBppVseaMsi=MJx7sSG_ODdM6I_1 I’m in Murrieta , CA, but I am only working on my family and friends cars right now. Thx for watching!

[@bacasloungemanta2007]

What to do if the issue is on the “other side”. It completely broke off the right hose (opposite side than on your video) The hose is not long enough to connect

[@bacasloungemanta2007]

The one that broke for me is the one that has green locks

[@CraigSodolak]

i have a 2014 and cant even see th etop of the tank

[@donlum9128]

It will also throw 430 cat code

[@jamieeisenhower1560]

What about Jeep Wrangler 2023. 2.0 Engine Gassy smell under the hood And you can't find it

[@DantheFixitMan]

@@jamieeisenhower1560 probably evap lines cracked or disconnected. I would try smoke test to see if anything shows up.

[@jamieeisenhower1560]

@@DantheFixitMan How do you do that

[@DantheFixitMan]

@@jamieeisenhower1560 I made that homemade smoke tester shown in the video, then just attached it to the evap lines.

[@peterzinia3767]

Ya & if you already live in Cali then go ahead & move. It has gone to hell in the last 20yrs.

[@GrumpyNCO]

Pro tip: don't live in CA

[@GrumpyNCO]

This video actually helped. Thank you from GA!

[@aquarius_babyj7539]

I have the same code; I live in NY. I will not pass inspection if this isn't fixed. If I take it to the shop, they'll probably mess around and charge me an arm and a leg.

Typical Jeep. Using a cheap plastic part.
