What Happens When Your Abs Sensor Goes Bad?

If your ABS system fails, you might notice it when braking heavily. A bad ABS module can cause the brakes to lock up even under normal braking conditions.

4 Bad ABS Wheel Speed Sensor Symptoms

The most common symptom of a malfunctioning ABS wheel speed sensor is an ABS warning light on your car’s dashboard. Other issues may occur when braking, such as decreased stopping distance or difficulty in controlling the car.

The main symptoms of a bad or failing ABS wheel speed sensor include:

Illuminated Warning Lights
Pulsating Brake Pedal while braking
Loss of Anti-lock Brakes
Loss of Traction or Stability Control

One of the most common signs that a wheel speed sensor on an automobile has gone bad is when the ABS control module will light up the ABS warning light and deactivate the system to prevent accidents. Other symptoms may include decreased acceleration or braking, or difficulty turning corners.

Illuminated Warning Lights

The dashboard contains a variety of lights that indicate when there is danger. When the ABS wheel speed sensor fails, the ABS light may be one of the first indications that something is wrong.

If the ABS warning light comes on, it may indicate that one or more of the car’s other systems are not working properly.

In rare cases, defective ABS wheel speed sensors can cause the speedometer to stop working.

Pulsating Brake Pedal while braking

If one of the ABS sensors fails, it can cause the car’s control module to mistakenly think that it is on a slippery surface, which will then trigger various safety measures.

The braking system will activate the ABS and traction control to help keep you from skidding. You will feel this by feeling a pulsating or pumping brake pedal while braking.

Loss of Anti-lock Brakes

Whenever a problem is detected with the anti-lock brakes, an alert is triggered and the ABS warning light comes on.

A fault has been detected in the vehicle’s electronic control module, which is causing it to lose valuable data from the sensor. This information is necessary for the computer to determine if there is a problem with the wheels and whether they need support.

The system is not able to determine what is happening, so the ABS shuts down until the problem can be fixed.

Loss of Traction or Stability Control

When the anti-lock brake system (ABS) sensor ceases to send information, the computer will disable other functions, such as stability control, traction control, roll stability and hill-start assist.

If you experience problems when driving in poor weather or braking quickly, it might be because the wheel speed sensor is not working correctly.

The problem could be caused by faulty wiring connections between the sensor and the engine control module (ECM).

ABS Wheel Speed Sensor Location

The ABS wheel speed sensor is located at the wheel, behind the brake rotor. However, some sensors are placed directly on the axle. This varies depending on the vehicle’s configuration.

Each wheel on an ABS-equipped vehicle contains one or more sensors that measure the speed of the rotating vehicle part. If there are four sensors, one will be at each wheel behind the rotor. If there are three sensors, two will be at each front wheel and another on the rear axle instead of at the wheels.

The four ABS configurations are: standard, electronic stability control with rollover mitigation, electronic Stability Control with traction control, and off.

An ABS system uses two sensors per wheel to detect when a wheel is locked up. If one sensor detects a lockup, the ABS system will engage at that point in the vehicle.

A three-channel, three-sensor ABS system monitors the movement of all four wheels simultaneously.

The rear wheels on a car use one controller to receive information from three sensors.

The ABS system uses four sensors to monitor the vehicle’s motion. Each sensor is located at a different wheel, which allows for more accurate readings.

ABS Wheel Speed Sensor Function

The ABS wheel speed sensor is a device that helps control the speed of your car by detecting when it has stopped on the road.

The ABS system is found on most new vehicles. It uses wheel sensors to measure the rotation speed of the wheels, and then sends that information to the controller. This system helps keep you safe during sudden stops or turns.

The controller calculates the speed of each wheel or axle. This data is then sent to the Engine Control Module (ECM).

When the ECM detects that one of the wheels is locking up, the ABS system will be activated. This rapid-fire operation can often cause a grinding noise and a pulsating sensation.

The vehicle’s ABS sensor helps to control the movement of the vehicle if traction is lost.

The computer reduces the amount of braking force being applied to the wheel, which causes trouble. When this force decreases, it allows the wheel to regain grip and rotate normally again. These same sensors run stability control systems in modern cars.

ABS Wheel Speed Sensor Replacement Cost

The average cost to replace an ABS wheel speed sensor is between $200 and $400, depending on the car model and labor costs. You can expect to pay around $100 to $150 for the wheel speed sensor itself, plus another $100 to$300 for labor.

Wheel speed sensors on luxury vehicles can often cost more, plus some models can be harder to work on, which increases the technician’s labor costs.

If you experience problems with your car’s wheel speed sensor, it is possible to replace it yourself with a few tools. However, this task can be difficult if the sensor becomes stuck.
