ABS (Anti-lock Braking System) speed sensors monitor the rotational speed of each wheel during braking. They help detect when a wheel is about to lock up, allowing the ABS control module to modulate brake pressure and prevent skidding. This enhances vehicle stability and control during hard braking situations. By maintaining traction, ABS speed sensors contribute to safer driving conditions.
if your speed sensors are failing you will get a light on your dash either abs or taction control light you will no longer have abs or trac control
One of the speed sensors runs the speedometer/odometer and transmission shift patterns, other speed sensors run the abs and or traction control.
where are the abs inop
It is a sensor that monitors wheel speed and sends that info to the abs module and/or the traction control module.
Usually the ABS and traction control off lights will come on

A Vehicle Speed Sensor (VSS) senses the speed of the vehicle. Used for automatic transmission shift points and other electronics. Another speed sensor would be a wheel speed sensor. This one monitors wheel speed for ABS and Traction control.
Probably one of your wheel speed sensors
The traction control and the ABS both use the wheel speed sensors in the wheel bearings
There are wheel speed sensors for the ABS and traction control systems and there is a vehicle speed sensor (VSS) that the ECM moniters and also operates the speedometer/odometer.
There are transmission speed sensors on the transmission and abs speed sensors for the wheels. The speedometer signal comes from the abs system.There are transmission speed sensors on the transmission and abs speed sensors for the wheels. The speedometer signal comes from the abs system.
