Crankshaft Position (CKP) Sensor Inspection
Visual Check
Check that O-ring is free from damage.
Check that end face of sensor and signal pulley tooth are free from any metal particles and damage.
Performance Check
1) Remove metal particles on end face of CKP 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 CKP sensor.
If resistance is out of specification, replace CKP sensor.
CKP sensor resistance
Vary from less than 220 Ω (ON) to infinity (OFF) or from infinity (OFF) to less than 220 Ω (ON)
