What are the Symptoms of a Faulty ABS Wheel Speed Sensor?

The ABS wheel speed sensor is a critical component of the Anti-Lock Braking System (ABS) and is used to detect the rotational speed of each wheel. If the ABS wheel speed sensor malfunctions, it can cause a variety of issues that can cause a vehicle to become less safe to drive or even prevent it from being driven altogether. Common symptoms associated with an ABS wheel speed sensor malfunction include:

1. Warning lights on the dashboard: Malfunctioning ABS wheel speed sensors can cause warning lights such as the ABS light, traction control light, and brake warning light to come on.

2. Loss of traction control: An ABS wheel speed sensor failure can cause the vehicle’s traction control system to become inactive, resulting in reduced stability when driving on wet or slippery roads.

3. Uneven braking: If only one wheel’s ABS wheel speed sensor is malfunctioning, it can result in uneven braking where one side applies more pressure than the other, making it difficult for the driver to control the vehicle.

4. Brake drag: When an ABS wheel speed sensor fails, it may cause one or more wheels to remain engaged even after releasing the brake pedal; this is commonly known as “brake drag” and will result in reduced fuel efficiency as well as increased wear-and-tear on brakes and tires.

If any of these symptoms are present, it is recommended that you have your vehicle inspected by a qualified mechanic and replaced if necessary.

Automobile – ABS Wheel Speed Sensor Symptoms
