The gas cap was the first thing I replaced. The error still persists...
In terms of recent work done on the vehicle, the only thing that is even remotely related to the engine is the drive serpentine belt which was replaced about two months ago. The error showed up even before this was done.
How can I troubleshoot the purge valve by the intake manifold as mentioned by JFP? I'm not even sure where the valve is located...
Thanks for your help!
