Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM.
This fault is logged when the ECM does not receive a valid camshaft position signal.
Possible causes:
1)Open or short circuit of the 5 volt SUPPLY, SIGNAL, or RETURN wire in the engine harness
2)Damaged or malfunctioning camshaft position sensor.
Possible repairs:
1)Replace the sensor.
2)Replace the engine wiring harness.
