P0340, P0345 CMP SENSOR
Description
The camshaft position (CMP) sensor senses the retraction of camshaft (INT) to identify a particular cylinder. The camshaft position sensor senses
the piston position.
When the crankshaft position sensor system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead,
utilizing timing of cylinder identification signals.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to change.
