How Do I Know If My ABS Sensor Is Broken?


The anti-lock braking system (ABS) sensor plays a crucial role in the functioning of your vehicle’s ABS system. It helps to prevent the wheels from locking up during braking, enhancing the overall safety and control of your vehicle. However, like any other electronic component, the ABS sensor can malfunction or break over time. In this article, we will discuss the signs that indicate a broken ABS sensor and what you can do about it.

Signs of a Broken ABS Sensor

1. ABS Warning Light

One of the most common signs of a broken ABS sensor is the illumination of the ABS warning light on your dashboard. The ABS warning light typically looks like an amber circle inside parentheses, and it illuminates when the system detects a fault in the ABS sensor or any other component of the ABS system.

2. Irregular Brake Functioning

A broken ABS sensor can affect the overall functioning of your vehicle’s brakes. You may experience irregular brake behavior, such as the brakes pulsating, engaging too easily, or not engaging when required. This can compromise your safety on the road, making it crucial to address the issue promptly.

3. Inconsistent Traction Control

The ABS sensor also plays a vital role in the functioning of the traction control system. If the sensor is malfunctioning or broken, you may notice inconsistent traction control. This can cause your vehicle to lose traction more easily, especially during harsh weather conditions or when driving on slippery surfaces.

4. ABS System Failure

In severe cases where the ABS sensor is completely broken or fails, the entire ABS system may shut down. When this happens, you will lose the benefits of having an ABS system, and your vehicle’s brakes will function without any assistance. This can be dangerous, especially during sudden stops or emergency situations.

What to Do If Your ABS Sensor Is Broken?

1. Check for Faulty Wiring or Connections

In some cases, a broken ABS sensor may simply have a loose or faulty wiring connection. Start by inspecting the wiring and connections leading to the ABS sensor. Look for any signs of corrosion, damage, or loose connections. If you find any issues with the wiring, repairing or replacing them may resolve the problem.

2. Clean the ABS Sensor

Over time, the ABS sensor can accumulate dirt, grime, and other debris, which can affect its performance. Use a suitable cleaning solution and a non-abrasive brush to gently clean the sensor. Be cautious not to damage the delicate parts of the sensor during cleaning. Once clean, check if the ABS warning light turns off. If not, further troubleshooting may be required.

3. Replace the ABS Sensor

If your efforts to fix any wiring issues or cleaning the sensor do not resolve the problem, it may be necessary to replace the ABS sensor. Refer to your vehicle’s manual or consult a professional mechanic to identify the specific ABS sensor that requires replacement. Once you have the new sensor, follow the manufacturer’s instructions to install it correctly.

4. Seek Diagnostic Assistance

If you are uncertain about the exact cause of the ABS sensor issue or unable to fix it yourself, it is recommended to seek diagnostic assistance from a professional. They have the necessary tools and expertise to identify the problem accurately and provide appropriate solutions. Additionally, they can also check for any other underlying issues with the ABS system that may have caused the sensor to break.

Preventing ABS Sensor Issues

1. Regular Maintenance

Regular maintenance of your vehicle, including timely inspections and services, can help prevent ABS sensor issues before they become major problems. Follow the recommended maintenance schedule provided by your vehicle’s manufacturer to ensure all components, including the ABS sensor, are functioning optimally.

2. Safe Driving Practices

Practicing safe driving habits can also help prevent ABS sensor damage. Avoid sudden stops, accelerate and decelerate gradually, and maintain a safe distance from other vehicles to reduce the risk of harsh braking situations that can strain the ABS system.

3. Keep the Wheel Speed Sensors Clean

Since the ABS sensor relies on the wheel speed sensors to function properly, it is essential to keep them clean and free from debris. Regularly inspect the wheel speed sensors for any signs of dirt or damage. If necessary, clean them gently with a suitable cleaning solution to maintain their effectiveness.

4. Address Any Warning Signs Promptly

If you notice any warning signs indicating a possible issue with the ABS system, including the ABS warning light, irregular brake functioning, or inconsistent traction control, it is crucial to address them promptly. Ignoring these signs can lead to further damage and compromise your safety on the road.


Recognizing the signs of a broken ABS sensor and taking appropriate action can help ensure the safety and performance of your vehicle’s braking system. Regular maintenance, safe driving practices, and prompt addressing of warning signs are essential to prevent ABS sensor issues. If you are unsure or unable to resolve the problem yourself, seek professional assistance to accurately diagnose and fix the underlying problem. By doing so, you can enjoy a safe and reliable driving experience.
