Description
Camshaft Position Sensor (CMPS) is a hall sensor and detects
the camshaft position by using a hall element.
It is related with Crankshaft Position Sensor (CKPS) and
detects the piston position of each cylinder which the CKPS can't detect.
The CMPS is installed on engine head cover and uses a target
wheel installed on the camshaft. The Cam Position sensor is a hall-effect type
sensor. As the target wheel passes the Hall sensor, the magnetic field changes
in the sensor. The sensor then switches a signal which creates a square wave.
