2003 GMC Sierra 1500 Problems

4WD Transfer Case Position Sensor/Selector Switch May Fail

The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.

Steering Wheel Position Sensor May Fail

The steering wheel position sensor may fail, resulting in the service stability message being displayed.

Fuel Level Sensor Failure

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
