I am also looking for a solution, but this is what I know so far. ( I am not a mechanic, so my word is not gospel) P-0455 code occurs when there is a fault in the EVAC system. The EVAC system uses vaccuum hoses and air pressure sensors to sense and determine the effevtiveness of certain internal systems. However, before you bring your car in for servicing, know this.... P-0455 can occur when you leave the gas cap offf!!! when it is back on tight, it should go away after a few engine cycles (a few long drives, or about a week). my car, however, keeps showing this code even after replacing my old gas cap and several trips to my mechanic. now he says I might have to bring it to the dealer.
What else can I help you with?
