evap system error 2002 Grand Cherokee
Thought it was fixed, but the error codes P0442 and P0455 have returned. Dealer replaced fuel tank under recall about 2 months ago and every thing seemed fine until a couple of days ago when once again the check engine light came on. Has anyone out there trouble shot this system at home? What are the most likely areas to cause this error. I cleared the codes yesterday and will see how long it takes them to come on. This is a frustrating problem. Also with the 2002, I'll need to remove the inner fender liner to get to the evap canister. Supposedly it is held on with special rivets.
