Vehicle Speed Sensor (VSS): 3.2TL

  1. Check fuse No. 9 (7.5-amp) located in underdash fuse/relay box. Check for open ground circuits between instrument panel gauge assembly 14-pin connector terminals C9, C10 and ground connector G501 located at lower left center of dash (both Black wires). Repair as necessary. If both ground circuits are okay, go to next step.
  2. Raise and support front of vehicle. Disconnect 14-pin connector from instrument panel gauge assembly. Connect DVOM between gauge assembly harness connector terminal C2 (Blue/White wire) and ground. 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, replace gauge assembly. If voltage does not toggle between zero volts and about 5 volts, go to next step.
  3. Connect DVOM between ECM 32-pin connector terminal No. 9 (Blue/White wire) and ground. Figure. While observing voltmeter, slowly rotate 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, repair open circuit in Blue/White wire between VSS, ECM, cruise control unit and driver's multiplex control unit. See appropriate wiring diagram in WIRING DIAGRAMS article.
  4. Disconnect 32-pin ECM connector. Check for short circuit in Blue/White wire between ECM connector terminal No. 9 and ground. Repair short circuit to ground in Blue/White wire between ECM, instrument panel gauge assembly, cruise control unit and driver's multiplex control unit as necessary. See appropriate wiring diagram in WIRING DIAGRAMS article. If no problem was found, check for bent, loose or corroded terminals. If all connectors are okay, replace ECM.
