Car speed sensor: its function and symptoms of damage The speed sensor in the car is used to measure the steering wheels, and it is one of the most important parts or sensors in modern cars, because many modern car systems rely on the information received from it, there is no doubt that the dynamic driving system (VDC) and the anti-lock brake system (ABS), And the automatic transmission system, urgently needs a speed sensor to complete its functions.

What is the function of the speed sensor in a car

The main function of this sensor is two things:

• Detecting and measuring the frequency signal caused by the wheel rotation, speed and transmission of the ABS system to provide the best brake efficiency when you use it, especially in emergency situations, in addition to achieving a sufficient distance to prevent collision.
• Monitoring the rotational speed of all wheels, sending data to the brake pump to adjust its pressure, prevent brake blockage on wheels and improve overall safety. It is very obvious that this sensor can measure the actual speed of the vehicle or car, and send this information to the main computer in your car for processing, and it should be noted that this sensor is different from the speed sensor in the transmission system inside the car, which in turn measures the rotational speed of the engine and not the speed actual car.

What are the signs of damage to the speed sensor in the car

The speed sensor in the car can only be checked using a voltmeter or a voltmeter, which is a device that you may not own, and if you have it, you may not be able to use it. Indicative of this, and to help you identify them, we have collected for you below some of them for you to see:

• Illumination of the ABS light in the dashboard.
• Poor performance of the ABS.
• Illumination of the custom light in the traction control system on the dashboard.
• Unstable engine performance when cruise control.
• Poor vehicle acceleration performance.
• Illumination of the engine inspection light.
• Other systems in the vehicle start to damage.

Find out why your car's speed sensor is damaged

There are many reasons that may lead to damage to the speed sensor in your car, and here you can see the most important of these reasons:

• A problem with the sensor connection to the main computer in the car.
• Dirt and debris build up on the sensor.
• Corrosion of electrical connections in the sensor.
• Increase pressure on the end of the wheel bearing.
• The sensor has been exposed to corrosion, which affects the empty space between the wheels and the sensor, thus taking false readings.
• The magnetic part of the sensor captures debris or metal particles.
