Hyundai Sonata: 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.
