Vehicle Speed Sensor

Vehicle Speed Sensor (VSS) is located at the rear of transfer case or transmission, and informs PCM of vehicle road speed. PCM determines speed of vehicle by converting a pulsing voltage signal from the VSS into miles per hour. PCM uses this signal to operate cruise control, speedometer, Torque Convertor Clutch (TCC) and transmission shift solenoids.
