ABS Sensor
While you may not give them a second thought during your daily commute, these small but mighty devices play a vital role in ensuring your safety and the smooth running of your vehicle. ABS sensors, short for anti-lock braking system sensors, are responsible for monitoring the speed at which your wheels spin.

By constantly analyzing this data, the ABS sensor provides real-time feedback to your vehicle's computer, allowing it to make split-second decisions that prevent your wheels from locking up during sharp stops or dangerous road conditions. In this step-by-step guide, we'll explore how ABS sensors work, their importance in accident prevention, and how to identify and fix common problems. So strap in and let's embark on a journey to understand the invaluable role the ABS sensor plays in your safety on the road.

ABS sensor: How it works

To understand the meaning ABS sensor, we must first understand how they work. ABS sensors are usually located near each wheel, either built into the wheel hub or attached to the brake rotor. These sensors use a magnetic collector or a Hall effect sensor to measure the rotational speed of the wheel. As the wheel rotates, the sensor detects the number of teeth or magnetic fluctuations that pass per revolution, producing an electrical signal proportional to the speed of the wheel.

The signal from the ABS sensor is then sent to the vehicle's computer, known as the Electronic Control Unit (ECU). The ECU processes this information and compares the rotation speed of each wheel. If the ECU detects a significant difference in speed between the wheels, indicating possible wheel lock, it activates the ABS system. The ABS system then momentarily reduces brake pressure on the affected wheel, allowing it to regain traction and prevent complete lockup.
