Camshaft Position Sensor: Testing and Inspection
Diagnosis of Camshaft Control
Diagnosis of Camshaft Control
The diagnosis of camshaft control checks the camshaft angle.
The diagnostic function is only activated if:
-
the engine speed lies in a defined range,
-
the engine oil temperature lies between its threshold's,
-
the fault flag of the power stage of the camshaft control is not set, and
-
the adaptation between camshaft and crankshaft has been performed.
If the actual camshaft angle differs for a certain time to the desired camshaft position, a camshaft positioning (plausibility) fault will be stored.
