For vehicles that have anti-lock brakes, the wheel speed sensor plays an important role. They work together with the electronic stability control system that is found on so many vehicles today.
This wheel speed sensor is responsible for keeping track of the wheel's rotational speed. This information is then transmitted to the ABS control module. Once this sensor starts to malfunction the Check Engine light may come on, the ABS light may come on, or the ABS system may stop working properly.
These sensors are typically built quite well so they hold up over time. One thing that can take a toll on them is road debris. Unfortunately, if you need to replace the wheel speed sensor it's not uncommon to have to replace the full hub assembly, since the sensor can be part of it.
Refer to your owner’s manual to learn about your vehicle’s wheel speed sensor. It’s best to have it inspected by a professional mechanic if you suspect there are issues with it. The mechanic will be able to properly assess the situation and provide you with pricing on the parts required. Be sure to ask if there is a warranty on the parts, and ask about the lifespan of them.
