Vehicle Speed Sensor (VSS)

Sensor is transaxle mounted. On 1.8L, the VSS turns a cable that is connected to the instrument cluster speedometer and transferred into a vehicle signal. On 2.0L A/T and 2.5L, VSS turns a Hall Effect sensor, which sends a constant pulse signal to PCM when vehicle is in motion.
