Vehicle Speed Sensor (VSS) On lower rear of transaxle, remove bolt and wiring connector and remove sensor from transmission, replace in reverse order !
VSS is a variable reluctance sensor that generates a waveform with a frequency that is proportional to vehicle speed. When vehicle is moving slowly, sensor produces a low frequency signal. As vehicle speed increases, sensor produces a higher frequency signal. The PCM uses this signal to control fuel injection, ignition timing and transmission shift points.
