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 logic prode to terminal A.
5. Rotate shaft slowly and check for ON/OFF battery voltage.
6. Connect a logic prode to terminal B.
7. Rotate shaft slowly and check for ON/OFF battery voltage.
8. Inspect rotor plate for damage or dust.
Replace the sensor if it fails the above tests.
