Crankshaft Position Sensor: Testing and Inspection

Fig. 131 Crank Angle Sensor Inspection:

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 positive lead of volt meter to terminals A and D, negative lead to ground.
5. Rotate shaft slowly and check for ON/OFF 5 volt supply.
6. Inspect rotor plate for damage or dust.
Replace the sensor if it fails the above tests.
