What is the importance and function of the Vehicle Speed Sensor (VSS) in Chevrolet Tracker?

The Vehicle Speed Sensor (VSS) is an important component in vehicles. The VSS is integrated into the speedometer and consists of a reed switch and magnet. The magnet's rotation with the speedometer cable causes the reed switch to turn on and off, generating a pulsing voltage signal that is sent to the PCM to calculate vehicle speed. If a failure occurs, code 24 is set. In the later models, the VSS is located on the side of the transmission or transfer case and consists of a Hall effect element, magnet, and gear. As the sensor gear is turned by a drive gear, the signal voltage switches back and forth in a square-wave form, with the frequency increasing in proportion to vehicle speed. This signal is sent to the PCM to control various devices, and a P0500 diagnostic trouble code is set if there is a problem in the VSS circuit.
