Description
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 respectively and use 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. So the sequential injection of the 6 cylinders is impossible without CMPS signal.
