Camshaft Position Sensor: Testing and Inspection

DISTRIBUTOR 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 - 0.4 mm (0.008 - 0.016 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
8. REINSTALL DISTRIBUTOR CAP
Install a new packing and distributor cap with the 2 bolts.
