The EGR valve position sensor shares supply and return wires in the engine harness with other sensors. Open circuits and shorts circuits in the engine harness can cause multiple fault codes to be active.
Possible causes:
1)Signal circuit open or shorted to ground
2)Supply circuit open or shorted to ground
3)Sensor shorted to ground
