Supra L6-3.0L DOHC Turbo (7M-GTE) (1987)
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.
