You count on your anti-lock braking system (ABS) each time you get in your car. Even when you don’t realize it, they are working to keep you and your passengers safe. Speed sensors are an integral part of that system and they play an important role in ensuring your brakes work when you need them the most.
WHAT ARE SPEED SENSORS?
Speed sensors are known by many names. They may be called the ABS sensor, ABS wheel speed sensor, ABS brake sensor, wheel speed sensor, or even an ABS speed sensor. All of these names refer to the same component, which calculates the number of times the wheels rotate to determine the speed of the vehicle.
The sensors are mounted on the wheel and provides information about the wheel. The ABS uses this information to make important calculations. It can determine if one wheel is slipping and if the brakes are requred in an emergency situation. Newer vehicles have more safety components, such as stability control and electronic traction control, which also utilize the speed sensors.
The number of sensors can vary with models. Some vehicles have a sensor on each wheel; other vehicles have them on the left and right of either the front or the back wheels. Some vehicles even come with three sensors with two on the front or back wheels and the third one on the rear axle.
As part of the ABS system, the sensors help ensure your brakes work perfectly to prevent an accident. It’s important to have this system checked and possibly replaced if you suspect any issues.
