What does a rear wheel sensor do?
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. When the wheel speed sensor is broken or not working as it should, one of the first things that are affected is the ABS system.
Is the wheel speed sensor the same as the transmission?
The wheel speed sensor is different than the speed sensor attached inside the vehicle’s transmission. Its job is to record the actual wheel speed and report this data to the vehicle ECU which controls all electronic functions on the car, truck, or SUV.
When to replace a bad wheel speed sensor?
1. ABS Light is illuminated on the dashboard Since the wheel speed sensor also monitors the anti-lock braking system on your car, it’s common for the ABS Light to illuminate when the sensor is worn out, disconnected, or has been struck by debris, which means you’ll have to replace the wheel speed sensor.
Where is the speed sensor on a car?
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.
How to replace the wheel speed sensor on a jeep?
Crawl up under the Jeep and you’ll see the sensor. Unplug the sensor then take an 8mm or 9mm (I don’t remember which) wrench an unbolt it. The sensor pulls straight out. Put some DE on the new one and slide it back in. Make sure the bolt hole lnes up and replace the bolt and plug it back in. Here is a pic of what the rear sensor looks like.

How many wheel speed sensors are on a car?
four wheel speed sensors
On most vehicles made in the last couple decades, there are four wheel speed sensors — one at each wheel. Signals from these sensors are used by the ABS computer to determine how quickly the car is slowing.
What kind of wheel speed sensor does ABS use?
Hall-effect sensors are often referred to as “active wheel speed sensors” and are more accurate than the magnetic type. On most vehicles made in the last couple decades, there are four wheel speed sensors — one at each wheel. Signals from these sensors are used by the ABS computer to determine how quickly the car is slowing.
How does a wheel speed sensor work on a car?
On most vehicles made in the last couple decades, there are four wheel speed sensors — one at each wheel. Signals from these sensors are used by the ABS computer to determine how quickly the car is slowing. If the computer senses that wheel lockup is about to occur, it commands the hydraulic modulator to pump the brakes.
What happens if I unplug the rear wheel sensor?
After a lot of looking and trial and error, I unplugged the rear wheel sensor and the problem stopped. My question is, since I unplugged the sensor do I still have all-wheel braking? A: If your ABS (or at least the system on your Buick) packs up, you’ll still have brakes on all four wheels, but without the benefit of the antilock feature.
