What kind of wheel speed sensor does ABS use?

Hall-effect sensors are often referred to as “active wheel speed sensors” and are more accurate than the magnetic type. On most vehicles made in the last couple decades, there are four wheel speed sensors — one at each wheel. Signals from these sensors are used by the ABS computer to determine how quickly the car is slowing.

What happens when your ABS sensor stops working?

It may also turn on the traction and stability control warning lights, if the car has those systems. Occasionally, the speedometer may stop working, as well. Loss of anti-lock brakes: Usually, the ABS computer will disable the ABS system if it detects a problem with a wheel speed sensor or its circuit.

How does Electronic Stability Control ( ABS ) work?

Electronic stability control improves vehicle handling and steering. To accomplish this, the ABS computer monitors changes in vehicle speed, momentum, steering and acceleration. This information is provided by a number of sensors, including the wheel speed sensors.
