Do You Have To Change Breaks Sensor At Same Time
The ABS bicycle speed sensor has multiple functions, making it a vital role of your automobile. When one begins to fail, you might notice several symptoms.
This commodity reviews the elevation for symptoms of a bad ABS cycle speed sensor, its location, function, and replacement cost. Permit's take a quick look at what signs you can look.
The almost common symptom of a bad ABS sensor is an ABS warning calorie-free showing up on your dashboard. You may also observe issues like a pulsating restriction pedal while braking or a complete loss of the anti-lock brake system.
As you lot can meet, at that place are actually not that many means to tell if an ABS sensor has gone bad. This is mainly because the ABS control module will light upwards the ABS alert light and deactivate the system to prevent accidents. Hither is a more detailed list of the well-nigh common symptoms of a bad ABS wheel speed sensor.
Bad ABS Cycle Speed Sensor Symptoms
1. Illuminated Warning Lights
Your dashboard contains a variety of important lights that alert you to danger. When the ABS wheel speed sensor fails, the ABS light is probably i of the first sign your will notice of all bad ABS cycle speed sensor symptoms.
At beginning, it might simply cause the ABS warning calorie-free to come on. All the same, when the other systems stop operation properly, you might also run across the traction and stability control warning lights.
In rare cases, lacking ABS wheel speed sensors tin cause the speedometer to end registering.

2. Pulsating Restriction Pedal while braking
The ABS sensors measure out the speeds of each bicycle, and if one of the ABS sensors has gone bad, it will read the wrong speed on ane or more wheels. This will cause the ABS command module to get tricked and thinking the car is sliding on a glace surface.
This will cause the ABS and traction control to kicking in, and yous will experience it by feeling a pulsating or pumping brake pedal while braking.
iii. Loss of Anti-lock Brakes
When an ABS wheel sensor fails, it causes the anti-lock brakes to be inoperable. Someday a fault is noticed, the organization triggers an warning, and the ABS warning low-cal comes on.
From hither, the vehicle's electronic command module stops receiving valuable data from the sensor. The computer relies on this data to decide if the wheels are locking up and crave support.
Because the system doesn't know what is happening, the ABS shuts downwardly until the repair is fabricated.
4. Loss of Traction or Stability Control
Non merely tin can you lose anti-lock brakes, but also other functions, such every bit stability control, traction control, whorl stability, and hill-start assist. When the sensor stops sending data, the computer shuts downwardly these systems as well.
However, y'all tin can experience problems even when the ABS light isn't on. If y'all struggle to maintain traction in poor weather condition conditions or notice treatment issues when you restriction quickly, the ABS bike speed sensor might be to arraign.
It could also be acquired by damaged wiring connections running from the sensor to the ECM.
ABS Wheel Speed Sensor Location
The ABS wheel speed sensor is located at the wheel, behind the brake rotor, but some are placed direct on the beam. Each vehicle contains a varying amount of ABS wheel speed sensors.
If the system contains four ABS wheel speed sensors, at that place volition be ane at each cycle behind the rotor. Systems with three sensors have 2 at each front end wheel and another on the rear axle instead of at the bike.
The ABS type determines how many sensors the vehicle contains. Here are four ABS configurations.
Two-aqueduct, iv-sensor ABS: One sensor is located on each wheel, just at that place's a channel in the forepart and one for the rear. When any speed sensors detect a wheel lockup, ABS engages at that part of the vehicle.
Three-channel, three-sensor ABS: There is one sensor located at each front wheel and one located on the rear axle. While the rear wheels are monitored at the same time, the front wheels are evaluated separately.
Three-channel, 4-sensor ABS: While there are sensors located at every wheel, the rear wheels run on i controller.
Iv-sensor ABS: One sensor is located at each wheel and monitored separately. This is the most common configuration with modern vehicles.
ABS Wheel Speed Sensor Office
The ABS wheel speed sensor can besides be called an ABS brake sensor or, more plainly, an ABS sensor. Whatsoever it is called, information technology is a critical part of the ABS.
The anti-lock braking system (ABS) is found on most new vehicles. ABS wheel sensors are attached to wheels or the axle to measure the rotation speed of the wheels. Most ABS sensors contain a toothed band and magnet that's enclosed with a coil. Contact between the magnet and band creates an electric field, which turns into the signal that is sent to the ABS controller.

From here, the controller determines the speed of each wheel or axle. This information is and so transmitted to the Engine Control Module (ECM).
When the ECM sees that a bicycle is locking up, the ABS is activated. Information technology operates at such a fast speed that it ofttimes creates a grinding noise with a pulsating sensation.
If the vehicle is also equipped with traction control, the ABS sensor helps control the movement of the vehicle in precarious situations. When traction is lost, the speed of one cycle will be different than the others, causing the system to kicking in.
The computer reduces the amount of braking force being practical to the wheel, causing trouble. When this force decreases, it allows the wheel to regain grip and rotate normally again. These aforementioned sensors run the stability control systems in modern cars besides.

ABS Wheel Speed Sensor Replacement Cost
The average ABS cycle speed sensor replacement cost is between $200 and $400 per sensor, depending on the car model and labor costs. You can look to pay about $100 to $150 for the wheel speed sensor and another $100 to $300 for the labor.
ABS wheel speed sensors on luxury vehicles tin often cost more, plus some models can exist harder to piece of work on, which increases the labor cost.
However, it'due south not difficult to replace the ABS wheel speed sensor yourself with a few tools. If you lot have basic mechanical noesis, this might exist a project worth tackling in your dwelling house garage. They can go stuck after a while though, so yous may demand some oestrus source to remove them.
