Vehicle Speed Sensor

Vehicle Speed Sensor (VSS) consists of a reed switch and magnet mounted on transmission. As magnet rotates within VSS, magnet causes reed switch to turn on and off. Switching action increases or decreases in proportion with vehicle speed. ECM supplies and monitors a voltage signal to VSS. ECM uses this signal to help determine control of idle speed control system as well as other control devices.
