- If the fault occurs only at a certain engine temperature, check the engine position sensor circuit while the engine is at that particular temperature.
- Check the camshaft end play to make sure that the camshaft gear is not moving too far away from the end of the engine position sensor.
- Check for moisture in the sensor harness connector at the ECM.
- Possible causes of this fault code include a damaged engine position sensor, short circuit, or an open circuit.
