Today we look at how to fix the check engine light caused by code P0456, P0240, P0442, P0440 for your 97-06 jeep wrangler tj, which most of them are a small evap leak in the evap emissions system. Could be from loose or cracked hoses or a loose or broken or missing gas cap. Go over how to fix this issue and what to look for. Hope this video helps out!

I realize that this video is over 2 years old, but that is the cleanest TJ engine bay I have ever seen

Ya because the loser isn’t even a true jeep owner and treats it like it’s a Lexus or smething lol he knows nothing about Jeeps and spends all his times shinning the rims on it instead of using it for it’s intended purpose

Had this code and ended up having to completely replace my charcoal canister and purge valve solenoid. I had the original charcoal canister on my '97 TJ, and it was totally broken, leaking charcoal into the solenoid and breaking that as well. I went with a generic charcoal canister as they don't make new ones specifically for the '97 TJ anymore and figured out a way to mount it under the hood. If you end up replacing the solenoid, make sure to go with an OEM solenoid and not an aftermarket one even though they seem exactly the same, as the aftermarket solenoid will end up tripping the check engine light again. Found that out the hard way.

On my 2001 TJ, it takes the sensors around 200 miles before they are all reporting in to the PCM. The evap sensor is the last to report. So when you clear the PCM, don’t think you’ve won till you drive it a while.

I'm *fairly* certain the steel line from the canister to the rubber hose back by the gas cap is corroded up behind the top of the spring mount on my '01 TJ. I'm going to put a new section in and see what happens. The EVAP code being thrown doesn't seem to affect performance or fuel economy - I'm just sick of looking at the MIL.

If you own a Wrangler you’re gonna have a evap issue. That’s just the way it is. Change out gas cap, evap canister, pcm and therm. Hopefully code clears after just 1 of the fixes, if not keep going down list

I have had a check engine light for 3 years. Evap large leak. 2004 4.0. I replaced the canister. No luck. Just poking around I followed the hoses FROM the canister. Found a hose that is completely overkill wrapped in electrical tape. Could this be the culprit? Hose connects directly to top of the canister and runs under the drivers side
