Camshaft Shift Angle Leeway, Intake/Exhaust

Measurement range: between -256 CA and +256 CA.

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). 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 deviate by more than between ± 10 degrees for longer than approximately 4 seconds.
