Kia Forte: 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.
