Camshaft Position Sensor: Testing and Inspection

CAMSHAFT POSITION SENSOR INSPECTION

NOTICE: "Cold" and "Hot" in the following sentences express the temperature of the coils themselves.
"Cold" is from - 10°C(14°F) to 5O°C(122°F) and
"Hot" is from 50°C (122°F) to 100°C (212°F).

1. DISCONNECT DISTRIBUTOR CONNECTOR
2. REMOVE DISTRIBUTOR CAP AND ROTOR
3. REMOVE IGNITION COIL DUST COVER
4. INSPECT AIR GAP





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

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

- If the air gap is not as specified, replace the distributor housing assembly.
5. INSPECT SIGNAL GENERATOR (PICKUP COIL) RESISTANCE





- Using an ohmmeter, measure the resistance between the terminals G (+) and G (-).

Pickup coil resistance:
Cold: 185 - 275 Ohm
Hot: 240 - 325 Ohm

- If the resistance is not as specified, replace the distributor housing assembly.
6. REINSTALL IGNITION COIL DUST COVER
7. REINSTALL DISTRIBUTOR CAP AND ROTOR
8. RECONNECT DISTRIBUTOR CONNECTOR
