Camshaft Shift Angle Leeway, Intake/Exhaust

Measurement range between -256° to +256°.

The value indicates the difference between the "Camshaft shift angle" (actual shift angle) and the desired value for the camshaft shift angle (target value for the engine control module (ECM)).

Ensure that the camshaft is operated by checking that the value of the "Camshaft shift angle" changes. Changing the "Camshaft shift angle" is achieved by changing the engine speed (RPM)/load.

The normal value varies depending on how far the camshaft is operated and the temperature/grade of the engine oil, although the value must never be higher/lower than between +/-10° for longer than 4 seconds.

HINT: Check the camshaft control function by choosing "Quick test camshaft control" in vehicle communication.
