Vehicle Speed Sensor (VSS) is located in speedometer assembly. Connect an ohmmeter between sensor terminals on back of instrument panel. See Figure -Figure .
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 for each revolution, replace sensor.
