LR023690G - ABS Sensor – FrontDescription: ABS Sensor Front for Defenders equipped with automatic transmission. This wheel speed sensor mounts at the front axle hub and continuously monitors wheel rotational speed. The signal is transmitted to the ABS control module, which compares readings from all four wheels during braking to detect impending lock up. When lock up risk is identified, the module modulates brake hydraulic pressure to maintain wheel rotation and steering control.
