ABS sensors are incredibly sensitive, individually monitoring the acceleration and deceleration of each wheel through an electromagnetic field generated by the wheel’s rotation. Fluctuations in this field are registered and sent as signals to the ABS controller unit, which instantly applies precise amounts of braking force to each wheel in order to boost performance and efficiency, as well as safety. Due to their proximity to the wheels and the ground, ABS sensors are exposed to constant heat, dirt and moisture, as well as vibrations and the occasional jolt; which can lead to malfunctions. Without reliable sensors, your ABS system can’t always keep you, your car and those around you safe, so taking the time to make sure your ABS sensors are of the highest quality is a must.
