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
