Vehicle Speed Sensor Test

Vehicle speed sensor is located on rear of instrument cluster. Connect ohmmeter between terminals "A" and "B". Terminals are located near vehicle speed sensor. See Fig 1 and Fig 2 .
Rotate speedometer cable shaft and note reading. Ohmmeter should deflect from continuity to no continuity 4 times per speedometer cable shaft revolution. Replace speedometer if reading does not deflect as specified.
