Crankshaft Position Sensor: Testing and Inspection

CRANKSHAFT POSITION SENSOR (CKP SENSOR)
The crankshaft position sensor, consisted of a magnet and coil, is located next to flywheel The voltage signal from this crankshaft position sensor is relayed to the ECM to indicate engine RPM and the position of the crankshaft.

Harness Inspection Procedure:

SENSOR INSPECTION
1. Disconnect the crankshaft position sensor connector.
2. Measure the resistance between terminals 1 and 2.
Standard value : 0.486 - 0.594 kohm at 20 °C (68 °F)




3. If the resistance deviates far from the standard value, replace the sensor.

Standard value
Clearance between the crankshaft position sensor and crankshaft position sensor wheel : 0.5 - 1.5 mm (0.020 - 0.059 in.)

Tightening torque
Crankshaft position sensor : 9 - 11 Nm (90 - 110 kg.cm, 6.6 - 8.1 lb.ft)
