Speed Sensor

The vehicle comes with various sensors, one such sensor is responsible for sensing the speed of the vehicle, and is known as a tachometer. It can also be said that it sensor wheel speed, and hence it is also referred to as a speed sensor. The purpose of a tachometer it to check the wheel rotational velocity, and apart from doing this main task it also behaves an input provider to other related systems such as the ABS and traction control which are safety control systems. ABS stands for Anti-lock Braking System. Replacing the tachometer is simple and doesn’t require much time as well.

It is often used to assess the current speed of the vehicle as seen on the dashboard of the vehicle. The ECU also uses this data to control functions such as the transfer change points, ignition timing, and the air-fuel ratio. To increasing the reliability, these sensors were introduced as a replacement to the mechanical sensors. With the introduction of safety systems such as ABS traction control system, velocity sensor data becomes even more important.

The vehicle speed sensor is located on the passenger side output flange inside the transmission frame.
