Vehicle Speed Sensor (VSS): Forester

  1. Disconnect VSS No. 2 and instrument cluster harness connectors. VSS is located on top front of transmission. Check resistance between VSS No. 2 harness connector terminal No. 1 and instrument cluster harness connector terminal No. 10. See WIRING DIAGRAMS  . If resistance is less than 10 ohms, go to next step. If resistance is not less than 10 ohms, repair or replace harness between instrument cluster and VSS.
  2. Check resistance between VSS harness connector terminal No. 2 and instrument cluster harness connector terminal No. 9. See WIRING DIAGRAMS  . If resistance is less than 10 ohms, go to next step. If resistance is not less than 10 ohms, repair or replace harness between instrument cluster and VSS.
  3. Check resistance between VSS terminals No. 1 and 2. If resistance is 350-450 ohms, go to next step. If resistance is not 350-450 ohms, replace VSS No. 2.
  4. Raise and support vehicle. Operate vehicle at speed greater than 12 MPH. Set DVOM on AC scale. Check voltage at VSS terminals No. 1 and 2. If voltage reading is greater than 5 volts AC, repair or replace speedometer. If voltage reading is not greater than 5 volts AC, replace VSS No. 2.
