Vehicle Speed Sensor (VSS): 3.5RL

  1. Check METER fuse No. 13 (7.5-amp). Fuse is located in underdash fuse/relay box. Disconnect VSS 3-pin connector. VSS connector is located on top rear of transaxle. Connect VSS Test Harness (07LAJ-PT30200A) to VSS harness connector. See Figure. Turn ignition on. Check for battery voltage between White test harness clip and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Yellow wire between VSS and METER fuse No. 13 (7.5-amp).
  2. Disconnect White test harness clip. Connect Green test harness clip to positive voltmeter probe. Measure voltage between ground and Green test harness clips. If 5 volts or more exist, go to next step. If less than 5 volts exist, repair short in Blue/White wire between VSS and PCM 16-pin connector terminal No. 13, cruise control unit 14-pin connector terminal No. 12, steering column control unit 12-pin connector terminal No. 11, driver's multiplex control unit 14-pin connector terminal No. 4, and/or navigation control unit 8-pin connector terminal No. 6. See appropriate wiring diagram in WIRING DIAGRAMS article.
  3. Turn ignition off. Disconnect test harness. Disconnect PCM 22-pin connector. See Figure. Check for continuity between PCM 22-pin harness connector terminal No. 22 (Green/Black wire) and VSS harness connector terminal No. 1 (Green/Blue wire). If continuity exists, go to next step. If continuity does not exist, repair open in Green/Blue or Green/Black wires between PCM 22-pin connector and VSS.
  4. Reconnect PCM 22-pin connector. Reconnect VSS Test Harness (07LAJ-PT30200) to VSS, in line, between harness and VSS connectors. See Figure. Connect Green test harness clip to positive voltmeter probe and Red test harness clip to negative voltmeter probe. Raise and support front of vehicle.
  5. Place transaxle in Neutral and turn ignition on. Block one front wheel. While observing voltmeter, slowly rotate other front wheel. If voltage toggles between zero volts and about 5 volts, go to next step. If voltage does not toggle between zero volts and about 5 volts, replace VSS.
  6. Disconnect instrument panel 22-pin connector "A". Measure voltage between ground and instrument panel 30-pin harness connector terminal No. 18 (Blue/White wire). While observing voltmeter, slowly rotate other front wheel. If voltage is toggling, replace speedometer. If voltage is not toggling, repair open in Blue/White wire between VSS and instrument panel 30-pin connector.
