Kia Stinger: Engine Control System / Camshaft Position Sensor (CMPS)

Specifications

Description and operation

Camshaft Position Sensor (CMPS) is a hall sensor, which 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 cannot be detected by the CKPS.

The CMPS is installed on engine head cover and uses a target wheel installed on the camshaft. The Cam Position sensor is a hall-effect type sensor. As the target wheel passes the hall sensor, the magnetic field in the sensor changes. The sensor then sends off a signal which creates a square wave which is used for precisely detecting the location of each cylinder to control the independent sequential injection of each cylinder.

Repair procedures

• DON’T remove the camshaft position sensor while the engine is running or right after engine is turned off. The part and engine oil is hot and can cause burns.

• Install the component to the specified torques. • Note that internal damage may occur when the component is dropped. In this case, use it after inspecting. • Apply the engine oil to the O-ring. • Insert the sensor into the installation hole and be careful not to damage it during the installation. • Be careful not to damage the sensor housing and the connector. • Be careful not to damage the O-ring.
