Beck/Arnley 084-5141 ABS Wheel Speed Sensor

The Beck/Arnley 084-5141 is an ABS wheel speed sensor, also called an ABS sensor or wheel speed sensor. It reads wheel rotation speed and sends that information to the vehicle's anti-lock brake system.

The ABS control module uses this signal to detect wheel slowdown or lockup during braking. A worn or failed wheel speed sensor can cause an ABS warning light, so replacing it helps keep the system working as designed.
