Inspection
Align timing mark on crankshaft vibration damper (6316) with the timing mark on the camshaft position sensor (CMP sensor) (6B288).
Remove camshaft position sensor electrical connector from camshaft position sensor.
Remove screw retaining the camshaft position sensor to the engine front cover (6019). Remove the camshaft position sensor.
Verify Top Dead Center (TDC) for No. 1 cylinder. Inspect camshaft position sensor bore in the engine front cover. Verify that the narrow gap vane on the camshaft drive gear is located in the middle of the bore.
If the narrow gap vane is at the top or the bottom of the bore, the camshaft timing is off one tooth and requires service.
If the narrow gap vane is not visible in the bore, reverify TDC No. 1 cylinder. If the narrow gap vane is still not visible, mechanical timing service is required.
Reinstall the camshaft position sensor.
Install the camshaft position sensor electrical connector.
