How much does ABS cost to fix?

ABS repair costs vary widely. In general, you’ll commonly pay around $100–$320 per wheel for sensor replacements, $800–$1,800 for replacing the ABS control module or hydraulic pump, and often around $100–$150 for diagnostic fees. A full system replacement can climb to $2,000 or more on some high-end vehicles.

What tends to cause an ABS problem

Understanding the common causes can help gauge whether you’re facing a sensor issue, a module failure, or something else, and how that translates to cost.

• Wheel speed sensor failure or wiring fault


• ABS control module or hydraulic pump failure


• Electrical issues such as blown fuses or damaged harnesses


• Stuck or leaking ABS actuator/valve block


• Low brake fluid or general brake system faults triggering ABS codes

Diagnosis is essential because symptoms can point to a specific part, and some fixes are simple replacements while others require extensive module work.

Cost breakdown by component

To give a clearer picture, here is how prices typically break down by the part involved.

• Wheel speed sensor replacement: Parts usually $20–$200; in many cases $60–$120 for labor, totaling roughly $100–$320 per wheel. If multiple sensors are affected, costs rise accordingly.


• ABS control module or pump replacement: Parts commonly $250–$700; labor $200–$500; total often $450–$1,200. In some models, OEM units or dealer work can push the price toward $1,500–$2,000.


• ABS actuator/valve block repair or replacement: Parts typically $300–$600; labor $200–$400; total around $500–$1,000. Replacing the entire hydraulic unit may be more expensive.


• Diagnosis and miscellaneous costs: Diagnostic fee commonly $80–$150; plus shop supplies; brake fluid flush if required.

Prices vary by vehicle make/model, region, labor rates, and whether you go with an independent shop or dealer. Some issues can be resolved with sensor cleaning or wiring fixes, while others demand expensive module replacements.

DIY vs professional repair

ABS systems are complex and involve safety-critical braking components. Most fixes should be done by a qualified technician. DIY work on sensors or wiring may be feasible for experienced hobbyists, but replacing an ABS module or hydraulic unit generally requires specialized tools and programming, and can affect vehicle warranty or safety systems.

What else can affect price

Several factors can push costs up or down, including the vehicle’s make and model, availability of parts, whether the repair is performed at a dealer or independent shop, and whether additional repairs are needed (e.g., brake fluid system, wheel bearings, or rotor replacement).

Summary

ABS repairs span a wide price range. Sensor-related fixes are usually the least expensive, while replacing the ABS control module or hydraulic pump is most costly. Always get a written estimate, consider a second opinion if the quote seems high, and address the ABS warning light promptly to maintain braking safety.

Can faulty ABS be repaired?

Yes, the ABS (Anti-lock Braking System) module can be repaired, but it is a complex job that should be done by a professional, as attempting a DIY repair can be dangerous. The most common component that fails is the electronic control module, which can often be repaired by sending it to a specialized company for rebuilding. Other, less common, failures might involve issues with the hydraulic unit, pump motor, or wheel speed sensors, which are also repairable.

Repair options

• Professional rebuild services: This is the most common and recommended method. You send your original module to a specialized company for repair, which can be significantly cheaper than buying a new one. The repaired module is then sent back to you, often plug-and-play, without needing to be reprogrammed to your vehicle's VIN. 
• Specialty mechanic: A mechanic with expertise in ABS systems can diagnose the problem and perform the repair, which may involve sending the module out for rebuilding or performing component-level repairs. 
• Component replacement: In some cases, individual components like the wheel speed sensors, pump, or a specific electronic component may be repairable or replaceable, but this requires specialized knowledge and tools. 

Why you shouldn't do it yourself

• Complexity: ABS modules are intricate electronic systems, and attempting repairs without the proper expertise and tools can lead to further damage or, more importantly, a safety risk. 
• Safety: A faulty ABS system can lead to dangerous situations, so it is critical to ensure that any repair is done correctly and by a qualified professional. 
• Lack of parts: Repair kits for individual components are not always available, and a professional service specializing in ABS module rebuilding can address common failure points.

How to tell if your ABS needs repair

• The ABS warning light is on.
• The brake pedal feels unresponsive or is spongy.
• Brakes lock up or fail to engage properly.
• You hear unusual noises, like clunking, when braking.
• Diagnostic tools show fault codes related to the ABS system, such as wheel speed sensor faults.

Can you drive with ABS failure?

Your brakes should still work even if your ABS has failed, so you will be able to drive the car, but you'll need to be extra careful, especially in an emergency. You'll need to keep in the front of your mind that there is nothing assisting you in heavy braking situations, so you'll need to drive accordingly.

How much is it to replace ABS in a car?

The average cost for ABS module replacement is $1174 to $1301. Enter your vehicle's information to see how much ABS module replacement costs in your local area.

What happens if you don't fix your ABS?

NOTHING adverse will happen. Fact is, your core is used in just about every exercise you do. Furthermore, your abs are there and will become visible once your body-fat percentage starts to drop below 14%, when you get under 10% they'll start to pop and cut; exercise or not!
