That helped so much, the gas cap on my Jeep was all twisted and not I fixed it and it solved the problem

[@ozzstars_cars]

Great, all fixed!

[@silvercoupe97]

Great video! It was pretty thorough. Thanks for going the extra mile to show the EVAP system...saving this for future review for my 04 TJ.

[@Marebo07]

Thank you!!

[@Ghost-oq4qj]

Lol 2002 tj problems you guys have to pull it apart for the smoke test 2003-2006 doesn’t

[@wbwright79]

thumbs up for great description of all parts involved. ended up locating my issue, due to seeing all the parts shown in your video, here, and checking them all individually.

[@ozzstars_cars]

Nice! Thanks

[@ajyankee]

I have a PA horn in the exact spot under the hood! Mines an 06 too. Gonna check everything you mentioned. Thanks for the upload!

[@scalefreakgaming]

Thanks for posting. Need to get mine out to take the body off

[@ozzstars_cars]

Have fun with all that rust! Yuck

[@TJsVette]

I keep getting the p0455 code but I don't have anything on the gas cap, guess I am going to have to start digging deeper and see if it's something else. I can replace the cap first and see if that works but I'm not going to get my hopes up lmao

[@ozzstars_cars]

Let us know when you find that small leak!

[@gmjunky87]

I wonder what kind of connector goes to the sensor of that evap can. Damn squirrels chewed the wires off mine.

[@ozzstars_cars]

The vapor leak detection pump connector? You can buy replacements or find one at a junkyard and splice it in. Soldering would be best using heat shrink tubing. ;-)

[@gmjunky87]

@@ozzstars_cars the canister that you removed, that plug that goes to the sensor, yeah those little buggers chewed it off! I think I'll try to take the plug apart and re wire it.

[@gmjunky87]

@@ozzstars_cars that plug you shined the flash light on @2:17

[@stevecurtis9408]

A daytime demonstration would really be helpful grrr

Sometimes the night is young and the timing is right. Thanks for commenting

Thanks for posting it was very helpful

[@timmckenzie9679]

What would be making a chattering noise in the area of the charcoal canister? On a cold day I clearly hear what sounds like a relay chattering in the canister area? The chattering started and I let it go until I started getting the small and large EVAP faults with the check engine light. Now I want to fix the system. I changed the solenoid in the engine bay and changed the gas cap...no joy and the chattering noise still persists. Have not done a smoke check and I have followed all lines I could and the lines look good. Any suggestions would be great.

[@ozzstars_cars]

The vapor leak detection pump is in the right rear near the canister. Let us know how it turns out.

[@timmckenzie9679]

@@ozzstars_cars Thank you for the reply. Would that pump make a chattering noise for a 20-30 second period only when the outside air temp is below 40 degrees or so? And if so, what would make it chatter like a relay making and breaking? I've had pumps whine when they start to fail but not chatter. Greatly appreciate anything you can provide to make me smarter on this system.

[@tjj5337]

That happen to my JK and it was fixed under warranty

[@chriskost9582]

Does this effect the way my jeep runs? Because mine has only the purge valve code and runs pretty rough

[@ozzstars_cars]

anything is possible. There could be a good size vacuum leak. Smoke test is the best bet to rule out the problem

[@Mattjki]

Thanks for thorough presentation.

[@davidwright1740]

I have a 2003 TV 4.0 and am trying to replace canister. What is the trick to getting that sensor plug to unplug? This thing has a couple of hard lines on the inside as well, and it doesn't seem that the entire canister and mount will slide out. Any suggestions? Great video! Thanks!

[@ozzstars_cars]

Did you slide the red tab back with a small pick or screwdriver first? Then unplug.

[@Kivavitch]

@@ozzstars_cars : I see the red sensor plug tabs, but don't understand when you say, " slide red tab back. " which direction are referring to?

[@ozzstars_cars]

@@Kivavitch slide it out, then press the tab and release the connector. It's a standard Chrysler locking clip.

[@Kivavitch]

@@ozzstars_cars : Never owned a chrysler, Chevy man myself. Never owned a Jeep either, a whole new learning curve. See the red tab w/ a small slot maybe for a small screw driver/sml. hook to pull on? how far does the tab slide out?

[@ozzstars_cars]

@@Kivavitch when you own a Jeep, you own a Chrysler. Red tab out using a screwdriver, pick or finger nail.

[@Msleelee9487]

well let me check my gas cap i replaced both camshaft position senors because thats what i had a code for and 2 days went by i still have better get up and go but check engine light came back on. i felt like i fixed it dang it back to the drawing board.

[@Fu81Z]

Does that also cause a hesitation while accelerating toward the top of each gear?

[@caleadfoter]

I have 2010 Jeep Liberty. It throws P0456 code. Already replaced gas cap, purge valve, canister and leak detection pump. Dealership wants to replace entire fuel tank system because they say there's "crack" on EVAP line fitting on fuel tank vapor control valve assembly. I asked if that part and hose can be only replaced? Dealership responded, no. I don't buy it. I have not yet to take it back to my local mechanic, but just that fuel tank vapor control valve and hose can be replaced without replacing entire tank, right? It runs little bit rough on idle.

[@ozzstars_cars]

The vent valve is a seperate part and can be replaced individually. Good luck.

[@ThomasC-Crazy4NiagaraFalls]

I was installing a trailer wiring harness and couldn't access the right side tail light connector without removing the charcoal canister. Left side was easy and took a couple minutes. I was losing patience with the right side trying to find the tail light connector and was on the verge of giving up and taking into the shop to have them do it. Thought I would try one more time, so did a search and came across your video. Thanks to your vdeo, I was able to move the canister out of the way and find the tail light connector. Finished the install on the trailer wiring harness and now I'm ready go camping. Thanks!

[@ozzstars_cars]

That's good news Tom! Glad the video helped you out. -Ozz

[@dadoofusbeats]

i didnt get a traditional code i got the number 710446 does that mean anything to anyone i cant find anything

[@carlwillis5505]

Ok, but after you cleared the codes, did they, or did they not, come back?

[@ozzstars_cars]

Fixed. No codes for that problem anymore.

[@carlwillis5505]

@@ozzstars_cars beautiful, thank you sir

[@JamesSmith-gj8kl]

Hey.. That's for the info.. Just bought a Jeep knowing it had an evap code.. but they didn't give me the code number.. you got me heading in a few directions.. It took 5 days before the code come on...I noticed that the purge vale was new(er) and the vacuum lines to it looked decent.. but I didn't know where the canister was and the gas cap didn't look too solid ..

[@ozzstars_cars]

Glad to help. Report your findings when you get the problem fixed.

[@JamesSmith-gj8kl]

So it turns out that the individual who installed the purge vale installed it upside down...

[@ozzstars_cars]

James Smith That would cause the MIL light to come on for sure! Good find and glad you got the problem resolved. Most times the problem is just something simple and small. Nice fix!

[@stevendominguez1130]

Great video, will try these methods. Thanks

[@ozzstars_cars]

Let us know how it goes Steven!

[@erickschaefer5886]

Great video man. Really helped. thank you.

[@ozzstars_cars]

Glad to hear it! You're welcome.

[@kickstart814]

Great informative video. Can you tell me what kind or where to get the metal plates you have in front of both doors? The plates attached to the front fenders with the logo cut into them. And also the rear plates with the rub rails on them. I can't locate either. Thanks a lot.

[@StressedBacon]

Dude lol that's a shitty place for the Evap canister. I got this code on my jk and now feel great because the JK's canisters are on the bottom of the jeep near the transfer case. Easy to get to and even easier to work with

[@ozzstars_cars]

Making it easy to fix broken stuff? That doesn't sound right lol

[@nathalye7909]

What kind of mechanic should I look for to fix this p0456 code on my Jeep Wrangler? Got a dealer quote a while back and they said I needed a new gas tank $500+

[@ozzstars_cars]

Someone who knows how to properly diagnose a problem before replacing ANY parts! Good luck.

[@se8214]

Thank you for the video!! I was able to fix an 06 wrangler and save hundreds!!!

Nice going!

What software are you using for diagnostics?

[@dad3562]

Did you ever find out what the issue was?

[@ozzstars_cars]

I sure did. Watch the full video. Your skipping Dad.

[@lenny0272]

what would cause my purge valve on the cainster to go on with no key on..since i parked it its buzzed on and off all nite..i can hear it from my kitchen....I am a frame tech but when it comes to this stuff i get lost...

[@ozzstars_cars]

Never heard of that in my life. If it is indeed the purge valve it's time for a wiring diagram and a test light. I wonder if the wiring is shorted to ground?

[@dannylamontagne7940]

very helpful , thanks for taking the time to show and explain it .

[@onlyoneromeo]

Is this the same procedures for the 4 cyl?

[@ozzstars_cars]

Yes, it's a real fkr for sure. haha Couldn't resist, I read your comment before the edit.

[@oscarlebron4678]

I purchased one over 10 years ago! It truly works on everything!

[@ozzstars_cars]

That's awesome man, keep on Jeeping!

[@MrSmocky]

will this cause you jeep to not start?

[@ozzstars_cars]

this is emissions related and has nothing to do with engine performance

[@MrSmocky]

Alright then it must be the ECM Iv already replaced fuel pump and fuel pump relay and the jeep sometimes starts but usually wont start a second time after i shut it off

[@premixjunkieify]

"Heat soak" / vapor lock . Check insulation/heat shield between exhaust manifold and fuel rail and injectors. If its damaged or missing, DEI makes a great inexpensive kit to fix your problems.... Keep JEEPing !!!

Not sure about that.
