Camshaft Position Sensor: Testing and Inspection

Camshaft Position (CMP) Sensor and Crankshaft Position (CKP) Sensor Inspection

Visual check
- Check that O-ring is free from damage.




- Check that end face of sensor and signal rotor tooth are free from any metal particles and damage.

Performance check
1. Remove metal particles on end face of sensor, if any.




2. Arrange 12 V battery (1) and connect its positive terminal to "Vin" terminal (2) and negative terminal to "Ground" terminal (3) of sensor. Then using ohmmeter, measure resistance between "Vout" terminal (4) of sensor and negative terminal of battery by passing magnetic substance (iron) (5) while keeping approximately 1 mm (0.03 in.) gap with respect to end face of sensor.
If resistance does not vary as specified, replace defective sensor.

CMP or CKP sensor resistance
Resistance varies from less than 220 Ohms (ON) to infinity (OFF) or from infinity (OFF) to less than 220 Ohms (ON)
