ABS Sensor Replacement Cost: Everything You Need to Know

To ensure a high degree of safety, modern vehicles employ a set of systems, and one such important system is the Anti-lock Braking System (ABS). The ABS system never lets your wheels lock up when you make an abrupt brake application, which helps you maintain control while braking and retake control of the car in the event of an emergency. The wheel speed is monitored by the ABS sensor, which is also known as the wheel speed sensor, that keeps observing the speed of each wheel all the time and sends this information to the ABS control module. A poorly working wheel speed sensor causes a degraded braking performance and an unstable safety system. Hence, we have put a thorough guide to help you learn more about the ABS sensor replacement and its cost in the UK.

What is an ABS Sensor and Why is it Important?

The ABS sensor is a small yet critical part, typically mounted near the wheels. It monitors the speed of the wheel and also transmits real-time information to the vehicle’s ABS system; helping an efficient and timely braking without skidding. Besides helping in braking control, ABS sensors also contribute to traction control and stability control systems of the vehicle. In its absence, these systems do not function normally and often fail driving regulation compliance in the UK.

Signs Your ABS Sensor Needs Replacing

Drivers do not always get signals of a faulty ABS sensor. However, there are some typical indications that may be a clear sign that your sensor is not working efficiently, which include:

• The ABS light comes on the dashboard, indicating a warning sign

• It takes longer to brake due to the sensor preventing ABS from activating when you need it most

• Strange vibrations or sounds through the brake pedal

• Loss of traction, letting the car feel slippery or unstable on icy roads

Hence, being vigilant to minor trigger signs causing a change in the functioning of the car can save you from injury.

ABS Sensor Replacement: How It Works

ABS sensor replacement is commonly an easy procedure for a seasoned car service professional. They simply remove the worn-out wheel speed sensor and mount a new sensor to the wiring, after cleaning the parts. 

It should be kept in mind that there are cases in which the issue is lodged deeper within the ABS control module itself. In those cases, swapping a sensor will not do you any good, and you may need to repair the ABS control module instead. A professional diagnosis prevents you from spending on parts that you do not really need.

ABS Sensor Replacement Cost in the UK

Among the biggest questions that drivers ask is: how much does it cost? On a standard basis, ABS sensor replacement cost in the UK is between £150 and £300, including part and labour.

Various factors may influence this cost:

• Car makes and models: Luxury or imported vehicles might come with more expensive sensors

• ABS system type: Advanced systems tend to employ more sophisticated sensors

• Labour costs: These vary from visiting a main dealer, local garage, or specialist

It is also important to compare the cost of wheel speed sensor replacement with repairing the whole ABS control module. Repairing the overall module may be a little more expensive, costing you somewhere between £500 and £1,000. However, it is the only choice left sometimes.

Initially, the OEM ABS sensors cost more, but they end up saving you money in the long term as they last longer and spare you from frequent replacements that get damaged faster.

Genuine vs Aftermarket ABS Sensors: Which Should You Choose?

When you are considering ABS replacements, you will generally be given the choice between genuine (OEM) or aftermarket sensors. Here is a glance at the differences:

• Genuine ABS Sensors (OEM):

Genuine ABS sensors are made by the same manufacturer that produces car models. Generally, they are backed by the brand warranty for structural defects and are also insured to fit precisely. Due to high manufacturing standards, they last longer.

• Aftermarket Sensors:

Aftermarket sensors are less expensive, but vary greatly in quality. Sometimes, you may get a high-quality product at a lower cost while other times cheaper products can be defective

• Long-term cost comparison 

Though more expensive in the beginning, genuine sensors are more dependable and longer-lasting compared to aftermarket sensors. Hence, OEM sensors are a wiser choice for saving on frequent repairs.

Common Mistakes Car Owners Make with ABS Sensor Replacement

Most car owners fall into these common mistakes when dealing with ABS sensor issues:

• Considering the price of products instead of focusing on their quality

• Delaying action until the problem is bigger

• Attempting to repair through DIY means without tools or experience

• Owners often do not recognise clear signs, and they end up replacing a sensor when the real issue lies within the ABS control module.

Steering away from all these mistakes will save you time and money.

How to Verify Authentic ABS Sensors Before Purchase

To avoid buying fakes or defective components, simply do the following:

• Check packaging for authenticity labels and part numbers

• Purchase only from reliable or genuine brands 

• If purchasing online, consider the car maker brand products

• Insist on warranty proof or maker's quality compliance

• Check vehicle original part numbers and specifications for a compatible fit

How ABS Sensor Affects Safety and Vehicle Value

Replacing the ABS sensor is not just about avoiding warning lights flashing, but about overall safety. A properly working ABS system reduces the risk of accidents and also saves you on insurance coverage. It even increases the vehicle's resale value. Thus, wisely investing in genuine ABS sensor replacement and professional fitting is not just about protecting yourself or your family but also increasing the long-term functionality of your car and its resale potential.

Conclusion

To keep you and your car safe, replacing the ABS system is important. If you perceive signs that your ABS wheel sensor might not be functioning properly, replacing it right away will keep your brakes and stability systems in working order as required. While the ABS sensor replacement cost in the UK may vary, a quality replacement is well worth purchasing in the long run.

FAQs

How to replace an ABS sensor?

To replace an ABS sensor, remove the wheel, disconnect the sensor plug, and take out the old sensor from the hub. Fit the new one, reconnect the wiring, and refit the wheel. It’s a simple job for a mechanic and manageable for confident DIYers.

How long does it take to replace the ABS sensor?

Usually between 30 minutes and an hour. It depends on how easy the sensor is to reach and whether any bolts are seized.

How does an ABS sensor work?

An ABS sensor monitors wheel speed and sends this information to the ABS control unit. If a wheel starts to lock, the system reduces brake pressure to keep control and prevent skidding.

How do you test an ABS sensor?

You can test an ABS sensor with a multimeter or diagnostic tool. Check the wiring first, then measure resistance or view live wheel speed data. A faulty sensor will show incorrect or no readings.
