What happens when a speed sensor stops working?
A speed sensor does not only indicate the vehicle speed but also help with cruise control operation and regulation of the fuel’s flowing and ignition timing. A speedometer may stop working due to a bad sensor.
Why is a speedometer called an eddy current?
They are often called eddy-current speedometers because they use magnetic eddy currents to display the speed of your car. Mechanical speedometers are analog devices that attach directly to the transmission shaft of the vehicle. They gave drivers a reliable way to measure their speed at a time when electronic sensors didn’t yet exist.
How does the magnet on a speedometer work?
This gear rotates with the mandrel, and is attached to the permanent magnet, which itself rests within the speedcup. As the magnet rotates, it creates a rotating magnetic field. This field then creates a drag force that pulls on the speedometer needle.

Why does my speedometer make a high pitched noise?
A high-pitched sound is generated by the metal core rubbing inside of the cable sheath. A speedometer head can also generate noise, which also spins along at the same speed. If you disconnect the cable from a speedometer head and it still makes noise, then you have just isolated the problem as the cable itself.
