Description and Operation: Description

• The Camshaft Position Sensor (CMPS) is a hall sensor, which detects the camshaft position by using a hall element.
• It is synchronized with Crankshaft Position Sensor (CKPS) and detects the piston position of each cylinder which cannot be detected by the CKPS.
• The two CMPS are installed on engine head cover of bank 1 and 2 (intake, exhaust) respectively and use a target wheel installed on the camshaft.
• Engine Control Module (ECM) detects the cycle of each cylinder based on the Camshaft Position Sensor (CMPS) signal and controls the fuel injection of each cylinder.
