What is speedometer or speed sensor?

As the name suggests, the speedometer displays your vehicle's speed in real time. Most speedometers are electronic. An electronic speedometer measures vehicle speed using a speedometer sensor. This sensor, usually located in the transmission, detects the rotational speed of the drive shaft. The sensor sends a corresponding series of pulses to ECU, which then converts these pulses into a digital number indicated by the speedometer. So when the speedometer sensor fails, the speedometer reading stops increasing.

When the speedometer sensor is not functioning properly, the Check Engine Warning Light should come on and your vehicle's cruise control will stop working. The speedometer may also stop working or become visibly inaccurate.
