Vehicle Speed Sensor (VSS): 2.5TL

  1. Check BACK-UP LIGHTS, METER LIGHTS, SUN ROOF ECU fuse No. 1 (10-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-PT3020A) to VSS harness connector. See Figure. Check for continuity between Red test harness clip and ground. If continuity exists, go to next step. If continuity does not exist, repair open in Black wire between VSS and ground connector located at left side of engine.
  2. Connect other end of VSS Test Harness (07LAJ-PT3020A ) to VSS connector. Connect positive voltmeter probe to White test harness clip, and connect negative voltmeter probe to Red test harness clip. See Figure. Turn ignition on. Measure voltage between White and Red test harness clips. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Yellow wire between VSS and BACK-UP LIGHTS, METER LIGHTS, SUN ROOF ECU fuse No. 1 (10-amp).
  3. Disconnect White test harness clip. Connect Green test harness clip to positive voltmeter probe. Measure voltage between Green and Red test harness clips. If 5 volts exists, go to next step. If 5 volts do not exist, repair short in Orange wire between VSS and PCM 16-pin connector terminal No. 13, Transmission Control Module (TCM) 22-pin connector terminal No. 5 and/or cruise control unit 14-pin connector terminal No. 12.
  4. Turn ignition off. Raise and support front of vehicle. Place transaxle in Neutral and turn ignition on. Block one front wheel. Wile observing voltmeter, slowly rotate one other front wheel. If voltage toggles between zero volts to about 5 volts, go to next step. If voltage does not toggle between zero volts to about 5 volts, replace VSS.
  5. Disconnect instrument panel 16-pin connector. Measure voltage between ground and instrument panel 16-pin harness connector terminal No. 3 (Orange wire). Wile observing voltmeter, slowly rotate one other front wheel. If voltage is toggling, replace speedometer. If voltage is not toggling, repair open in Orange wire between VSS and instrument panel 16-pin connector.
