Kia Carens: Engine Control System / Camshaft Position Sensor (CMPS) Description and operation
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.
