Hyundai Santa Cruz: Engine Control System / Camshaft Position Sensor (CMPS)

- Description 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 cam carrier 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.

1.Check the signal waveform of the CMPS and CKPS using the diagnostic tool.

Specification : Refer to "DTC Diagnostic Guide"

• Install the component to the specified torques.

• If a part is dropped, replace it with a new one and discard the dropped part as invisible damage may be caused.

• Apply the engine oil to the O-ring.

• Insert the sensor in the installation hole and be careful not to damage it.

• Be careful not to damage the sensor housing and the connector.

• Be careful not to damage the O-ring.

1.Install in the reverse order of removal.
