FUNCTION AND OPERATION PRICIPLE
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 two CMPS are installed on engine head cover of bank 1 and 2 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.
