An ABS (Anti-bolt Braking System) is an improved braking mechanism which is generally found in newer vehicles. An ABS sensor is a sort of tachometer that measures the rotational speed of a wheel and passes the wheel’s speed to the Engine Car Module (ECM). ECM is a computer that stores the information of the engine and all the systems attached to the engine. The ABS sensor is additionally called the wheel speed sensor or ABS brake sensor.
The main purpose of ABS sensor is to note the speed of all four tires and pass it on to the ECM. The ABS sensor generally comprises of a toothed ring and a magnet encased inside a loop. As the tire moves, the ABS sensor makes a connection of the ring and magnet which initiates a spark and hence initiate an electric signal. This electric signal then sends the information to the ABS controller. The controller at that point decides the speed of each wheel appropriately.
ABS sensor is present in every vehicle with ABS braking system, but the size of the sensor may vary in different vehicles. The size of an ABS sensor can depend upon the size of truck or manufacture.
Role of ABS sensor:
Later models are outfitted with some kind of traction control where the ABS sensor plays an important role in controlling the movement and speed of tires. Amid lost traction, the paces of the wheels on one side of the vehicle will be not the same as those on the opposite side. These circumstances are the point at which the onboard PC can control the braking energy to the wheels, and accomplish the coveted footing.
The ABS sensor is the principal sensor that keeps the braking energy of a vehicle in line. The sensor transmits the rotational data to the ECM to signal that one of the tires is bolted up, in which case, the PC will bring down the measure of braking power connected to the wheel being referred to. As the braking power minimizes, the wheel would now be able to turn and recapture its grasp. Numerous advanced vehicles additionally have ABS sensors which connect with the electronic traction control frameworks and stability control system to guarantee vehicle wellbeing.
Problems with ABS sensor:
Exposure to dust and dirt can cause the problems to the sensor. Cleaning your ABS sensor is important as it controls the flow and speed of wheels. Any problem with the ABS sensor causes the ABS light or traction control system light in the dashboard to glow. Indications of a terrible wheel speed sensor likewise incorporate an impressive misfortune in footing when you are driving on tricky street conditions.
Sometimes, the issue comes out to be with the wiring or connectors. So before driving your truck to an auto mechanic, make sure to find out where the problem lies. If the problem is with ABS sensor because of dust; you can clean your ABS sensor at your home.
For example, a messy ABS wheel sensor can make the framework trigger the ABS light amid your ABS PC’s self-assessment cycle. This sensor is likewise utilized as a part of some traction control systems, so on the off chance that you have a footing control, or against slip cautioning enlightened you may find that cleaning the ABS sensors will cure this, too.
How to clean?
In order to clean, try and remove the tire from your vehicle. If you can’t remove the tire of your truck, get some help or drive your vehicle to an auto workshop. Find the ABS wheel sensor. Remove the nuts and bolts from the wheel.
Also, remove the bolts that connect the wheel to the car’s engine. Remove the ABS sensor from your car to clean it. Remove the ABS sensor gently.
You can simply clean the ABS sensor of your truck using a piece of cloth. For better cleaning, utilize a suction vacuum and clean the sensor as well the axle thoroughly. Don’t use any kind of chemicals on the sensor. Chemicals affect the ability and performance of ABS sensors. ABS sensors are made from tough material and hence can be cleaned with ease. Remember this when working with these sensors, They’re tough, however, a little auto taken while you benefit the stopping automation en route can spare you from another exorbitant repair added to the brake benefit.
Once clean, reinstall the sensor back in its place. Attach the wires and connectors in the perfect way. Clean the wiring and connectors. Also, clean the bolts before putting them back. Reinstall your tire and you are good to go. Often; the ABS light doesn’t go off even after cleaning the ABS sensor. This is not a serious issue. ABS light takes up a few days to turn off. Drive your vehicle and do a braking test before driving on a long route.
In case of any misunderstanding regarding dissembling and assembling, consult a professional.
