Vehicle Speed Sensor
- VSS is located on top of differential assembly. See Figure . Ensure fuse No. 13 (7.5-amp) in passenger compartment fuse/relay box (located behind left kick panel) is okay. If fuse is okay, go to next step.
- Disconnect 3-pin harness connector at VSS. Turn ignition on. Measure voltage between Yellow wire of 3-pin harness connector and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair open Yellow wire.
- Measure voltage on Blue/White wire between 3-pin harness connector and ground. If voltage is 5 volts or greater, go to next step. If voltage is not 5 volts or greater, repair open or short to ground in Blue/White wire between VSS and PCM.
- Turn ignition off. Disconnect PCM harness connector "D". Check for continuity in Green/Blue wire between VSS 3-pin harness connector and PCM harness connector "D" terminal No. 22 (Green/Black wire). If continuity exists, go to next step. If continuity does not exist, repair open Green/Blue wire between VSS and PCM.
- Raise and support vehicle. Place transaxle in Neutral. Turn ignition on. Rotate one front wheel while holding other front wheel stationary. If voltage pulses from zero volts to about 5 volts or greater, go to next step. If voltage does not pulse as specified, replace vehicle speed sensor.
- Disconnect instrument cluster 30-pin connector. Measure voltage on Blue/White wire between instrument cluster 30-pin connector and ground while rotating one front wheel and holding other front wheel stationary. If voltage pulses from zero volts to about 5 volts, replace speedometer. If voltage does not pulse as specified, repair open Blue/White wire between VSS connector and speedometer.
