Can I change the ABS sensor on my own?
Anti-lock braking systems are standard in most current vehicles (ABS). The valves, controller, and speed sensor that make up this system all work together to ensure that you can brake safely.
The ABS speed sensor keeps track of how the wheels turn and ensures that the ABS system is activated if there is any slippage or difference. The controller is instructed to activate the ABS if this sensor detects a discrepancy, which overrides your manual braking.
Most current automobiles have ABS speed sensors installed at the wheels. The best place to mount them is here. Some vintage automobiles, particularly trucks with solid axles, will have them installed on the back differential. Simply a magnetic sensor, the ABS speed sensor creates a voltage as the tone ring slots or ridges move across its magnetic field. A modern car uses this kind of sensor for a variety of systems. This kind of sensor can be attached to anything that spins so that the powertrain control module (PCM) can keep track of its rotation.
You can swap out the ABS speed sensor on your own if it stops working or malfunctions.
What does it cost to replace an ABS sensor?
Depending on the automobile model and labor expenses, the cost to repair an ABS wheel speed sensor typically ranges from $200 to $400 per sensor. The wheel speed sensor will cost you between $100 and $150, and the labor will cost you between $100 and $300.
Luxury cars frequently have more expensive ABS wheel speed sensors, and some types can be more difficult to repair, which drives up labor costs.
With a few tools, you can easily replace the ABS wheel speed sensor on your own. This can be a project worth taking on in your garage if you have some basic mechanical expertise. However, they can get trapped after a while, so you might need a heat source to get them out.
Why do ABS sensors stop working?
The reluctor wheel or tone ring can quickly get dusty or damaged due to its position. Likewise, dust can amass on the sensor. Both could provide an unpredictable signal or none at all. Additional typical reasons for failure include:
- wiring/sensor winding breaks brought on by extreme vibration
- Short circuits inside
- more space between the wheel and the bearing
- Damage that occurred when replacing other braking parts
I have a damaged wheel speed sensor. Can I still drive?
It is realistic to assume that many drivers frequently prioritize mechanical issues with their cars depending on a variety of factors, including the expense of repair or replacement. Sometimes motorists believe that as long as the car doesn’t break down, a damaged sensor or a dashboard warning light can be fixed later on. However, a seemingly unimportant error with wheel speed sensors could become a significant safety hazard. Because of this, it is often dangerous to operate a vehicle with a damaged wheel speed sensor.
Unless you are driving on slick pavement, you probably won’t immediately notice much of a difference in how your car functions if the wheel speed sensor becomes broken or wears out. It might appear unimportant because your normal brakes are still functioning properly. Unfortunately, if you think this is the case, you have a false sense of security.
How can you identify the bad ABS wheel sensor?
A special kind of tachometer known as an ABS sensor measures the speed of a wheel and transmits that data to the ABS control unit. This data is used by the control unit to assess whether one or more wheels are locking up and likely to skid.
When a skid is detected, the control unit initiates the ABS system, which rapidly pulses the brakes on and off. This keeps the car from slipping and the wheels from locking up.
Checking the car for codes is the simplest technique to determine whether an ABS sensor is defective. Typically, ABS codes will start with the letter C. You can check for fault codes associated with the broken speed sensor by pinning a code reader or scanner into the OBD-II port.
If your ABS light is on, can you drive?
As regular braking is unaffected by the ABS light, you can continue to operate the vehicle while it is illuminated. However, since your ABS system aids in stopping control and driving without it can be risky, we wouldn’t advise you to do this. You want to know how your car will function if something goes wrong. Without a fully functioning ABS system, your car could not respond to hard braking as it should.
How long do ABS sensors last?
A professional can remove your car’s tires and replace the ABS speed sensor if one of your ABS speed sensors malfunctions.
The majority of contemporary cars include anti-lock braking systems (ABS), which enable you to brake forcefully while also steering and dodging any approaching objects in an emergency. Each wheel on your car has a separate ABS speed sensor. The ABS system will be completely disabled if one of them malfunctions, thus a bad speed sensor needs to be changed right away.
Each wheel has a speed sensor, which may be changed for somewhere between $200 and $400. They should typically be changed every 30,000 to 50,000 miles.

A automobile has how many ABS sensors?
An improved braking system called an ABS (Anti-lock Braking System) is frequently featured in more recent cars. An anti-lock brake sensor, often known as an ABS sensor, measures the rotational speed of a wheel and transmits the information to the engine control module of the vehicle (ECM). The wheel speed sensor and ABS brake sensor are other names for the ABS sensor. The ABS sensors communicate the speeds of all four wheels to the ECM, which uses this information to evaluate whether the wheels are locking up since no two wheels rotate at the same speed. Compared to traditional brakes, the ABS brake applies more quickly. As a result, in some cars, the ABS generates a grinding sound when it is activated.
Location:
In earlier ABS setups, the sensors were placed in components like the differential housing and steering knuckle that were external to the wheel hub. A ring gear is connected to the ABS sensor. The ring is attached to parts like the brake rotor and drum. In more recent systems, the wheel hub assembly itself houses the ABS sensors. The number of ABS sensors in a vehicle can range from one to four, depending on the sort of braking system it has.
Mechanism:
A magnet contained in a coil and a toothed ring often make up an ABS sensor. A signal is produced as a result of the electric field that is induced by the contact between the ring and the magnet. After that, this signal is converted to a digital signal and transmitted to the ABS controller. The controller then chooses the appropriate speed for each wheel.
The basic sensor depicted above is one that may be found on a Honda, but sensors vary in appearance and size from vehicle to vehicle.
The ABS sensor is essential for managing the movement of the car in all circumstances in the majority of later models that come with some sort of traction control. The speeds of the wheels on one side of the car will differ from those on the other after a loss of traction. In these circumstances, the on-board computer can control the braking force applied to the wheels in order to maintain the desired traction. The primary sensor that regulates a car’s braking capacity is the ABS sensor. When one of the tires is locked up, the sensor signals the ECM by sending rotational data, and the computer will then reduce the amount of braking force supplied to that particular wheel. The wheel can now turn and regain its grip when the amount of braking force drops. In order to assure vehicle safety, many modern cars now incorporate ABS sensors that communicate with the electronic traction control and stability control systems.
Symptoms of an ABS sensor failure:
The ABS sensor may stop working over time as a result of exposure to dirt and other contaminants on the road. For the sensors to operate at their best, cleaning and examining them at the intervals recommended in the user manuals is essential. The traction control or ABS light on your car’s dashboard turning on is one of the primary signs that an ABS sensor is malfunctioning. When you are driving on slick roads, you will notice a significant loss of traction, which is another sign of a malfunctioning wheel speed sensor.
It should be remembered that the ABS sensor may not always be the problem; faulty cabling or connectors may also prevent the necessary signals from reaching the ECM. Therefore, it is a recommended practice to inspect its linked components and identify the appropriate part that is at fault before evaluating and replacing the ABS sensor.
Is changing a wheel speed sensor challenging?
Step 1 is to set up your workspace. Make sure the car is level and on a safe surface, and that the parking brake is engaged.
Loosen the lug nuts in step two. Before you lift the car into the air, loosen all of the lug nuts using a lug nut socket set and a 1/2 inch drive breaker bar.
3. Jack up the car and utilize jack stands. The car is raised and placed on jack stands. Place the wheels away from the work area, over to the side.
Make careful to jack up the car in the proper spot. You can often jack up the car from pinch welds on the sides underneath. Make sure the stands are on the body or frame before lowering it onto them.
Remove the outdated wheel speed sensor in step four. In some circumstances, you might need to take the brake rotors and pads off in order to see the wheel speed sensor clearly. The bolt holding the sensor to the hub/knuckle can be removed once it is visible.
Next, unfasten any clamps or hold downs holding the sensor wiring to the chassis or body of the car. Once you’ve done that, unplug it to enable total removal from the car. To make sure the new sensor fits smoothly, use some emery cloth or sandpaper to remove any rust from the regions where it will go.
Install the brake components and wheel speed sensor in step 5. Reverse the order of the steps you took to eliminate everything as you work. The replacement connector should first be plugged in before the wiring harness is routed back and fastened to the body or chassis. After that, put it into the hub or knuckle.
Reinstall the brake caliper bracket, brake rotor, and brake pads if you have to remove the brakes; make sure to torque everything to the manufacturer’s specifications.
Reinstall the wheels in step six. Utilizing the lug nuts, reinstall the wheels onto the hubs. Use a ratchet and socket to tighten them all down.
Step 7 is to jack up the car again and remove the jack stands. Put the jack in the proper location below the car and raise it until you can take the jack supports off. The car can then be lowered back to the ground.
Step 8: Apply wheel torque. Most automobiles employ a torque range of 80 to 100 ft lbs. SUVs and trucks often use 90 to 120 foot pounds of torque. To ensure that the lug nuts are torqued to the correct specification, use a 1/2 inch torque wrench.
Step 9: Take the car for a test drive. The ABS and traction control lights need to turn off when the wheel speed sensor has been changed. If they don’t, you’ll need to take it to a qualified mechanic to have the computer on the car reset.
To test your ABS and make sure it is functioning properly, drive down a safe road where you may accelerate quickly and apply the brakes firmly.
With the proper equipment and understanding, replacing a wheel speed sensor is a pretty simple task. However, if it’s a job you don’t want to do yourself, the qualified mechanics at YourMechanic can replace the wheel speed sensor for you.
What occurs if the speed sensor fails?
The powertrain control module won’t be able to properly control the gearshifts if there isn’t a speed signal coming from the sensors. The transmission won’t function correctly as a result. Either more rapidly than anticipated or more roughly than anticipated.
