Code P0455... Help!
heys guys,
so checked out the code, and checked my car... no leaks around the tank, new gas cap... What else can it be? I clear the code, but it comes on after a few hours of driving. Has anyone experienced this issue?

There was a similar post on this Cel code not long ago... But I think the consensus was the missing gas cap or maybe you ran the car with the gas cap open? I believe Loren also recommended to check on the ventilation line that is attached to the Evap canister system, or ventilation line that is detached from the tank, or something related to the ventilation line in general. Let us know if you found the root cause to this Cel code. Good-luck...
