The anti-lock braking system (ABS) speed sensor is vital because it keeps track of the wheel rotation. As the component calculates the speed, it delivers the data to the vehicle computer which is necessary to decide if the ABS should be engaged.
ABS wheel speed sensor functionThe wheel speed sensor is the main data source for the ABS, so for the ABS control module to function properly, there are wheel speed sensors located on all four wheels. Once you start driving sensors are always sending the speed of each wheel to the ABS control module. These wheel speed sensors are placed in the hub, where they can track how fast the axles are rotating.
Common issues with a faulty ABS wheel speed sensorA faulty ABS wheel speed sensor can lead to loss of traction control, an unstable vehicle while braking, and it may take longer for your vehicle to halt
