Description and operation

Crankshaft Position Sensor (CKPS) detects the crankshaft position and is one of the most important sensors of the engine control system. Lack of CKPS signal may cause the engine to stop. Installed on the cylinder block or the transaxle housing, it generates alternating current by magnetic flux field made from the sensor and the target wheel during engine runnig.

The target wheel consists of 58 slots and 2 missing slots on 360 degrees CA (Crank Angle).

Repair procedures

Check the signal waveform of the CMPS and CKPS using the KDS.

Specification: Refer to "Wave Form"


Switch "OFF" the ignition and disconnect the negative (-) battery terminal.


Disconnect the crankshaft position sensor connector (A).


Remove the installation bolt (A), and then remove the crankshaft position sensor.

Crankshaft position sensor mounting bolt:

9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)


Install the component to the specified torques.

Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.

Apply the engine oil to the O-ring.

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


Install in the reverse order of removal.
