Vehicle Speed Sensor

The Vehicle Speed Sensor (VSS) is a part of your vehicle's ant-lock braking system (ABS). In addition the output from the VSS is also used for the odometer to read the vehicle's speed and for your vehicle's automatic transmission to switch gears according to the speed of your vehicle. The ABS is a vehicle safety mechanism that maintains the vehicle's tractive contact with the road during braking. The engine control unit (ECU) works in conjunction with a number of sensors and hydraulic valves to control the braking action. The ECU needs to constantly monitor the speed of the wheels in order to kick the braking system into action when needed.
The sensor is essentially a tachometer device that measures the transmission or transaxle speed and sends the information to the ECU. The VSS has a toothed ring and a voltage generator. The voltage generator generates a constant voltage in between its own permanent magnet and coil. This constant voltage is disrupted periodically by the rotating teeth of the ring to generate a pulse output which is sent to the ECU for interpretation of the speed of the vehicle.
If the VSS fails, it would result in the improper activation of the ABS system. This would also cause your odometer to malfunction and your transmission will switch gears incorrectly. A visual indicator of a fault in the sensor is when the Check Engine light goes on in your dashboard. If you notice any of these signs in your vehicle, take a good look at your vehicle speed sensor. The sensor is susceptible to damage from debris from the road or even if you have recently done some repairs on your wheels.
