Diagnostic of Camshaft Position Sensor



Diagnostic Of Camshaft Position Sensor

The purpose of this function is to control the signal change of the camshaft position sensor.

If the signal during a fixed number of engine revolutions continuously is high or low a max or min fault is detected.

If there is no regular alternating of the signal (change of high and low with revolution of the camshaft) for a fixed cycle, a plausibility failure is detected.
