Crankshaft Position Sensor: Testing and Inspection

INSPECTION

1. Turn the ignition switch OFF.
2. Disconnect the connector at the distributor.




3. Using an ohmmeter, check the resistance of the Crankshaft Position Sensor (pick up coil) at terminals NE+ and NE-. resistance should read:

Cold: 185 - 275 ohms
Hot: 240 - 325 ohms





4. Using a thickness gauge, measure the air gap between the signal rotor and the pickup coil.

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

NOTE: The air gap is not adjustable. If any of the above tests reveal a pick-up coil outside specifications, replace the distributor housing assembly.
