Speed Sensor
- Disconnect the speedometer from transmission. Check for continuity between terminals 13 and 9 in control unit connector as speedometer is turned by hand. See Figure.
- Continuity should be indicated 4 times for each full turn of the cable. If continuity is not as specified, remove gauge assembly, and check for continuity between terminals X and Y as speedometer cable is turned. See Fig 1.
Connector is viewed from wire side.
- Continuity should be indicated 4 times for each full turn of the cable. If okay, there is an open circuit in the wiring harness from gauge to control unit. If not okay, speed sensor is defective.
