- It is a type of tachometer that measures the rotational speed of a wheel.
- The ABS operates by preventing the wheels from locking up during braking.
- The ABS sensors report the speeds of all the four wheels to the ECM.
The ABS sensor usually consists of a toothed ring and a magnet enclosed within a coil. The contact between the ring and the magnet induces an electric field due to which a signal is generated.
This signal is then transformed into a digital signal and sent to the ABS controller. The controller then determines the speed of each wheel accordingly.
The ABS sensor is the main sensor that keeps the braking power of a car in check. The sensor transmits the rotational information to the ECM to signal that one of the tires is locked up.
Many modern vehicles also have ABS sensors that interact with the electronic traction control systems and stability control systems to ensure vehicle safety.
