When any of the speed sensors detect a wheel lockup, ABS engages at that part of the vehicle.

What happens when the wheel speed sensor does not work?

ABS does not work properly The anti-lock braking system is designed to apply smooth application of brake fluid to engage the brake calipers and pads to slow your car without locking up the tires. The wheel speed sensor is responsible for relaying the wheel speed to the ECU so that it can tell the ABS system how much pressure to safely apply.

This component, which is also referred to as an ABS sensor, is attached to the hub of a drive tire and is responsible for monitoring multiple vehicle functions such as traction control, anti-lock braking systems, and obviously, the vehicle’s speed.
