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 50°C (122°F) and
"Hot" is from 50°C (122°F) to 100°C (212°F).

1. REMOVE DISTRIBUTOR CAP





- Remove the 2 bolts, and disconnect the distributor cap from the distributor housing.
2. REMOVE ROTOR
3. INSPECT AIR GAP





- Using SST, measure the air gap between the signal rotor and pickup coil projection. SST 09240-00020

Air gap: 0.2 - 0.45 mm (0.008 - 0.018 in.)

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





- Using an ohmmeter, measure the resistance between terminals.

Pickup coil resistance:
Cold: 135 - 220 Ohms
Hot: 175 - 255 Ohms

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