Vehicle Speed Sensor: Testing and Inspection

1. Remove the meter hood.
2. Remove the instrument cluster.
3. Loosen the screws for the A and B terminals.

NOTE: If the screw is loosened excessively, it will disengage from the speedometer, and you will not be able to measure the resistance properly.

4. Connect an ohmmeter between terminals A and B of the speedometer.
5. Verify that the ohmmeter needle pulsates while rotating the speedometer shaft with a screwdriver.
