Crankshaft Position Sensor: Testing and Inspection

Crank Angle Sensor Test:

1. Leaving terminal connected, remove crank angle sensor.
2. Disconnect power transistor connector (to prevent electrical discharge from the ignition coil, avoiding possible electrical shock).
3. Turn ignition switch on
4. Connect a volt meter between terminal 3 and ground.
5. Rotate shaft slowly and check for ON/OFF 5 volt signal.
6. Connect a volt meter between terminal 4 and ground.
7. Rotate shaft slowly and check for ON/OFF 5 volt signal.
8. Inspect rotor plate for damage or dust.
Replace the sensor if it fails the above tests.
