Four Symptoms of a Faulty ABS Wheel Speed Sensor
ABS sensors assess wheel speed, and if one of them fails, it might cause
serious problems. Here are several frequent indicators that your sensor is
ABS wheel speed sensor serves a variety of purposes, making it an important
component of your vehicle. You may notice a number of signs when one's
condition begins to deteriorate.

ABS warning light appears on your dashboard as the most prevalent indicator of
a faulty ABS sensor. You could also notice a pulsing brake pedal or a full
failure of the anti-lock brake system while braking.

your car and discover that a prior failure was due to the ABS light being on,
it's possible that the problem was caused by broken wheel speed sensors.
you can see, there aren't many indicators that an ABS sensor has failed. This
is because, in order to avoid accidents, the ABS control module will illuminate
the ABS warning light and deactivate the system. Here's a more in-depth look at
the most prevalent signs of a faulty ABS wheel speed sensor:
1. Warning Lights -
Illuminated A number of crucial lights on your dashboard warn you of impending
danger. The ABS light is likely one of the first signs of problematic ABS wheel
speed sensor symptoms when the ABS wheel speed sensor fails.It might merely
cause the ABS warning light to illuminate at first. When the other systems stop
working correctly, the traction and stability control warning lights may
illuminate as well. If this occurs, go online and look for car repairs near me
to schedule an appointment with a certified technician. Defective ABS
wheel speed sensors might cause the speedometer to cease registering in rare
2. Pulsating Brake Pedal -
While braking, the ABS sensors detect the speeds of each wheel, and if one of
the ABS sensors fails, it will read the incorrect speed on one or more wheels.
The ABS control module will be deceived into thinking the vehicle is sliding on
a slick surface as a result of this. Because this is an unsafe, search online
for car services near me
and schedule an appointment with a repair garage as soon as you notice a
pulsing brake pedal.The ABS and traction control will activate as a result, and
you may notice a pulsing or pumping brake pedal while braking.
3. Anti-lock Brakes Failure -
When an ABS wheel sensor fails, the anti-lock brakes become inoperative. When a
malfunction is detected, the system sends out an alarm, and the ABS warning
light illuminates. The electrical control module of the car then ceases
receiving crucial data from the sensor. This information is used by the
computer to evaluate if the wheels are locking up and need assistance. Because
the ABS system has no idea what's going on, it shuts down until the problem is
4. Loss of Traction or
Stability Control - Other issues, such as stability control, traction control,
roll stability, and hill-start assist, might all be lost. The computer turns
off these systems when the sensor ceases delivering information. Even if the
ABS light is turned off, you may have troubles. The ABS wheel speed sensor
might be to blame if you have trouble maintaining traction in bad weather or
notice handling concerns when braking rapidly. Damaged electrical connections
between the sensor and the ECM might also be to blame.
Function of an ABS Wheel Speed Sensor
ABS wheel speed sensor is often known as the ABS brake sensor or simply the ABS
sensor. It is a vital aspect of the ABS, whatever it is named.
new cars are equipped with an anti-lock braking system (ABS). ABS wheel sensors
detect the rotation speed of the wheels and are mounted to the wheels or axle.
A toothed ring and magnet, encased in a coil, are found in most ABS sensors.
When the magnet and the ring make contact, an electric field is created, which
is converted into a signal and supplied to the ABS controller.
controller regulates the speed of each wheel or axle from here. This data is
subsequently sent to the Engine Control Module.
ABS is initiated when the ECM detects a wheel that is locking up. It runs at
such a high pace that it frequently emits a grinding sound along with a
ABS sensor helps manage the movement of the vehicle in risky conditions if the
vehicle also has traction control. When traction is lost, one wheel's speed
differs from the others, forcing the mechanism to engage.
computer causes problems by reducing the amount of braking force given to the
wheel. When this force is reduced, the wheel is able to acquire grip and
revolve normally once again. The stability control systems in modern vehicles
are also controlled by these sensors.
