Hi there,\012

These codes are for the fuel system the system performs a pressure test when the vehicle reaches a certain speed for a certain period of time, predetermined from the factory. The Gas cap is the most likely suspect.  Disconnecting battery will reset (and delete) all error codes and clear the check engine light, VSC, etc. idiot lights on the dash.

Post further comments if further you have the same problem....

Good Luck!!
