It is probably a sensor that goes by the gas tank. I belive it is called a Fuel Vent Sensor Circuit. That should fix the problem.

5.Connect the new EVAP vent solenoid harness (3), P/N 22687059, to the EVAP vent solenoid (2), route the harness above the rear ABS harness (4) and connect the EVAP vent solenoid harness (3) to connector C313 (1).
6.Lower the vehicle.
7.Clear the DTC's with the Tech 2 scan tool.
If all of the wires are good you will want to check for any leaks in the evap system.
