P0455-"A large Evaporative Emission Control System leak has been detected."
Usually it means that your gas cap is not on tight, or the seal is old and wont seal tighly. For some reasons, that code comes on for me whan i unplug the AIT sensor even when the engine is off, the code usually goes off within a day however.
Large emission vapor leak. Check the gas cap and all lines from the tank to the engine.
