Camshaft Position Sensor: Testing and Inspection

INSPECTION





1. Inspect air gap; Using Special Service Tool or equivalent for G1 and G2 pickups and a feeler gauge for the NE pickup, measure the air gap between the signal rotor and pickup coil projection (SST 09240-00020 for G1 and G2 pickups).

Air gap: 0.2 - 0.5 mm (0.008 - 0.020 in)

If the air gap is not as specified, replace the distributor housing assembly.

2. Disconnect Distributor Connector.





3. Inspect Pickup Coil resistance; Using an ohmmeter, measure the resistance between terminals.

Pickup coil resistance (Cold):
G1 and G (-): 125 - 200 Ohms
G2 and G (-): 125 - 200 Ohms
NE and G (-): 155 - 250 Ohms

Pickup coil resistance (Hot):
G1 and G (-): 160 - 235 Ohms
G2 and G (-): 160 - 235 Ohms
NE and G (-): 190 - 290 Ohms

If the resistance is not as specified, replace the distributor housing assembly.

NOTE: "Cold" and "Hot" in the preceding tests express the temperature of the coils themselves. "Cold" is from -10°C (14°F) to 50°C (122°F) and "Hot" is from 50°C (122°F) to 100°C (212°F).
