Hyundai Creta: 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. This sensor has a hall-effect IC which output voltage changes
when magnetic field is made on the IC with current flow.
