Gas cap?....................

Reinstall it or get a new one. Make sure it clicks when you tighten.

Code will clear after a couple hours of driving if its the issue.

Most likely it is. let us know.

Somewhat self-explanatory. There is flow being sensed through the purge line when the purge valve should be closed. In the evap system, fuel vapors are captured from the tank and stored in the charcoal cannister. At a pre-determined time, like right after startup (someone help me out here if I don't have it exactly right), the purge valve opens for a short time and the collected vapors are sucked into the intake system to be burned with normal combustion; then the valve closes until next time. I don't know if that particular code would indicate a leaking purge valve, but that would be a possibility.

Here's some more info:
