Camshaft Position Sensor: Testing and Inspection

INSPECTION OF CAM POSITION SENSOR

1. INSPECT AIR GAPS




Using a feeler gauge, measure the gap between the signal rotor and pickup coil projection.

Air gap: 0.2 - 0.4 mm (0.008 - 0.016 in.)

If the gap is not within specification, replace the cam position sensor.

2. INSPECT PICKUP COILS




Using an ohmmeter, check resistance of the pickup coils.

G1 pickup coil resistance:
G1 -> G- 140 - 180 Ohms

G2 pickup coil resistance:
G2 -> G- 140 - 180 Ohms

Ne pickup coil resistance:
Ne -> G- 140 - 180 Ohms

If the resistance is not within specification, replace the cam position sensor.
