P0440 Evaporative Emission Control System Malfunction Posted in the PCM forum
Any help would be much appreciated. I posted it over there because I had a Scanmaster question.
Thanks guys!

It's either the gas cap (simple and cheap) or it's a valve on the top of the tank (requires dropping the tank, not simple or cheap)
I had the same code the first week I had my T/A, they had to drop the tank, and replace some valve that's up there (at least that's what the service manager told me they did)

The gas cap wasn't on tight. Thanks!
