CAMSHAFT POSITION SENSOR - SIGNAL GENERATOR 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. 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 - 0.4mm (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.

Pickup coil resistance (G + and G -):
Cold: 185 - 275 ohms
Hot: 240 - 325 ohms

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