I have a P0455 code, reads evaporative emmissons control system gross leak. Any thoughts? Dont notice any change of power or anything. Any help is greatly appreciated.
I had the same thing, it was just the gas cap...put it on and pull real hard on it. If it pops off then try putting it on again or get a new one if you can't seem to get it to stay on.
You reset it and it came back? I know on most vehicles it goes away on its own after driving for a while. Purge solenoid valve, the cap is normally the first thing to try though.
