Re: Check Engine Light -- P0456
You've opened a two year old post. Best to open a new thread to get more exposure. A loose gas cap or bad cap seal will generate a P0456 code. Inspect vacuum lines especially the elbows leading to and from the leak detect pump underneath near the engine craddle the EVAP canister and purge valve. A shop will connect a smoke machine and look for smoke escaping from the system. http://www.obd-codes.com/p0456
