Vehicle Speed Sensor (VSS)

The VSS is an electronic relay that is mounted on the transaxle. As the transaxle turns the VSS, the VSS provides the speedometer with a vehicle speed input (voltage pulses). This input is used to drive the speedometer. The speedometer then converts the Vehicle speed input into a more precise waveform and provides the Powertrain Control Module (PCM) and the cruise control module with its own vehicle speed input. The cruise control module converts this input into a vehicle speed. For vehicle speed sensor replacement procedures, refer to Vehicle Speed Sensor Replacement in Automatic Transmission - 3 Speed, Vehicle Speed Sensor Replacement in Automatic Transmission - 4 Speed or Vehicle Speed Sensor in Manual Transmission - MB4 and MB5.
