yes, you're screwed!!......jk, it may be as simple as your gas cap not being screwed down properly..... give it a try and get the ecu reset.

i think the 455 is the same code associated with the purge valve solenoid, but i would have to double check that.

Could be as simple as a gas cap having been left loose. Or your carbon canister is bad and not scrubbing the gas fumes clean...Reset it and drive if it stays off gas cap was culprit. If it comes back on see your dealer to do a evap sys leak check.

i had the 0455 come up and whenever i had it scanned it showed loose or no gas cap...so i tightened it down good (atleast 3 clicks) and then went and loosened the negative battery terminal for about 10 minutes while i was helping a friend work on his car and then hooked everything back up and voila! no more CEL
