Crankshaft Position Sensor: Testing and Inspection

AIR GAP INSPECTION



1. DISCONNECT DISTRIBUTOR CONNECTOR.
2. REMOVE DISTRIBUTOR CAP.
3. REMOVE ROTOR.
4. INSPECT AIR GAP.

The NE Pickup Coil Is The Crankshaft Position Sensor:

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

Air gap: 0.2 - 0.5 mm (0.005 - 0.020 in.)

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


SENSOR RESISTANCE 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)
Hot is from 5O°C (122°F) to 100°C (212°F).




- Using an ohmmeter, measure the resistance between terminals.

Resistance (NE to G-)
COLD: 155 - 250 Ohms
HOT: 190 - 290 Ohms

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

6. REINSTALL ROTOR.
7. REINSTALL DISTRIBUTOR CAP.
8. RECONNECT DISTRIBUTOR CONNECTOR.
