ABS Sensors monitor wheel speed and send the information to the Engine Control Module (ECM). The computer adjusts the anti-lock braking system to equalize wheel speeds and prevent the brakes from locking up in an emergency, allowing the driver to maintain control of the vehicle. Older configurations of ABS had the sensors located outside the wheel hub. Newer systems are fitted in the wheel hub assembly itself. Depending on the system, vehicles can have only one ABS Sensor or as many as four. more details on - https://www.carid.com/pex/rear-driver-side-abs-speed-sensor-mpn-411-279.html
