The Delphi ABS Wheel Speed Sensor - SS20043 is a high-quality sensor designed to accurately measure the speed of a vehicle's wheels. It is specifically designed for use in vehicles equipped with an anti-lock braking system (ABS). The sensor is responsible for detecting the rotational speed of each wheel and relaying that information to the vehicle's ABS control module. This allows the ABS system to adjust braking pressure and prevent wheel lock-up during sudden braking or slippery road conditions. The Delphi ABS Wheel Speed Sensor - SS20043 is a reliable and durable component that helps ensure the safe operation of a vehicle's braking system.
