Vehicle Speed Sensor

  1. Vehicle Speed Sensor (VSS) is located in speedometer assembly. Connect an ohmmeter between sensor test terminals on back of instrument panel. See Fig 1 .
  2. Rotate speedometer cable. For each revolution of speedometer cable, sensor should make and break continuity 4 times. If ohmmeter reading does not fluctuate between continuity and no continuity or if sensor does not make and break continuity 4 times per revolution, replace sensor.
