Speedometer Head: Testing and Inspection

Speedometer Pins:

1. Remove speedometer assembly from the cluster.
2. With ignition switch in On position, check for battery voltage across B+ pin and ground pin.
3. Check for continuity in wire between distance sensor signal pin and distance sensor.
4. If wiring continuity is OK, test for a faulty distance sensor. SEE Computerized Engine Controls.
5. If distance sensor proves good, replace the speedometer.
