Checking Components And Connectors

Check the camshaft position (CMP) sensor and control module connectors. Check for contact resistance and oxidation.

Check that the camshaft position (CMP) sensor is correctly installed and that neither the sensor or the housing is damaged. Damage may affect the position of the sensor in relation to the camshaft rotor.

Try a new camshaft position (CMP) sensor if no fault is found during the above fault-tracing.

Remedy as necessary.
