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

- 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 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 changes in the sensor. The sensor then switches a signal which creates a square wave.

- Inspection

1.In the engine control system, failure can be quickly diagnosed by using the diagnosis tool.

(1)Self diagnosis : Checking failure and code number (DTC).

(2)Current data : Checking the system input/output data state.

(3)Actuation test : Checking the system operation condition.

(4)Additional function : Controlling other features including system option setting and zero point adjustment.

Component Inspection

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

Specification : Refer to "DTC Diagnosis Guide"

- Removal

• DON’T remove the camshaft position sensor during engine running or right after engine stops, or a scald by the flowed out engine oil may occur.
