What is the Speedometer Sensor all about?

As its name implies, the speedometer displays your vehicle's real-time speed. Most speedometers are electronic. An electronic speedometer measures vehicle speed with the help of a speedometer sensor. This sensor, usually located at the transmission, detects the drive shaft's rotational speed. The sensor delivers a corresponding series of pulses to a computer, which then turns these pulses into the numerical figure the speedometer indicates. So when the speedometer sensor becomes faulty, the speedometer becomes unreliable.
