Transmission Range Sensor (TRS)
Disconnect negative battery cable. Disconnect harness connector at TRS on side of transmission. See Fig 1 . Using an ohmmeter, ensure continuity exists between indicated sensor terminals in specified gear range. See TRANSMISSION RANGE SENSOR RESISTANCE table. Ensure continuity does not exist between specified terminals and ground. Replace TRS if it does not test as specified.

- Disconnect negative battery cable. Remove instrument cluster. Connect ohmmeter between VSS and GND terminals on back of instrument cluster. Insert screwdriver into speedometer cable connector. Rotate screwdriver. See Fig 2 .
- Ohmmeter reading should alternate between zero and infinity 4 times for each revolution of speedometer head. Replace speedometer if VSS does not test as described.
