The control parameters of a car are vital for security during the drive. They should perform up to the mark, and anything below the standard can lead to a major accident with rollover effects. Talking about these control parameters, you can’t exterminate wheel speed sensors from the list as they occupy a top position. These sensors are also called ABS sensors and monitor the wheel rotation speed to send it to the ABS control module. These sensors are vital in sports cars as their wheels rotate too quickly. This post will leave no stone unturned regarding ABS sensors. Keep reading to learn more!
What are Wheel Speed Sensors?
Other names for the wheel speed sensors include ABS sensors and ABS brake sensors. They monitor each tire’s rotational speed and provide the vehicle’s engine control module with performance data (ECM). Every wheel in an automobile rotates at a different rate. The ECM examines the sensor data to determine which wheels are locking up.
These sensors collaborate closely with the vehicle’s sophisticated electronic systems to maintain optimum driving dynamics, lower fuel consumption, and lower gas emissions. The wheel speed data collected by sensors are transmitted through data lines from the ABS control unit to various vehicle components.
A wheel speed sensor is crucial in sports cars as these machines rotate wheels faster. The ABS sensors will make more sense in sports cars than in ordinary cars.
What are the Different Types of Wheel Speed Sensors?
Wheel speed sensors sometimes differ, depending on the vehicle model and nature. However, there are two general types of these sensors that you can find in the books. These are explained in the coming lines.
i) Active Wheel Speed Sensors:
Only when the active wheel speed sensor is given a voltage and produces an output signal is it considered “activated.” Active wheel speed sensors generate a digital signal delivered to the ABS control unit. Because they have a detecting element coupled to either a magnetic element or a two-pole electric cable, active wheel speed sensors are also known as magneto-resistive sensors.
Digital signals can determine how the wheel turns and are more accurate at slow speeds; the active sensor is more effective than a passive sensor.

ii) Passive Wheel Speed Sensors:
Passive speed sensors, also called inductive or variable-reluctance magnet sensors, function without needing an additional voltage source. The impulse wheel, which is attached to the drive shaft, is above it. When the impulse wheel turns, the sensor measures the speed.
This causes a change in winding from tooth to tooth, which in turn causes a change in the magnetic flow. The ABS control module transforms the AC signal from the passive sensor, created in response to the wheel’s speed, into a digital signal.
What are the Causes of Faulty Sensors?
Wheel speed sensors will not perform accurately sometimes, and you better seek the reasons/causes. They must perform well as they are essential for the optimal performance of your car. Here are a few failure causes that you must know:
- Driving with increased wheel bearing clearing
- Broken wiring of the sensors
- Disrupted signal generation
- Heavy contamination of sensors
- Internal short circuits
- Mechanical damage to the wheel encoder
- External damage that impairs the speed sensors
Once you spot the root cause of faulty ABS sensors, you should get it fixed quickly to keep your wheels rolling.
What are the Signs of a Faulty Wheel Speed Sensor?
Your vehicle will perform abnormally if there is a faulty wheel speed sensor. However, it takes a technical mind to listen to an unusual voice while driving a car on the highway. Here are a few signs you should notice to determine your wheel speed sensors demand immediate attention.
- ABS warning light switched ON
- The traction Control warning light switched ON
- The fault code is stored
- Loss of traction on the slippery road surface
- Wheel locking during the brake
Each wheel may include one to four ABS sensors, depending on the wheel type. The ABS sensors are crucial to a vehicle’s ABS working properly. The two different types of wheel speed sensors inform the ABS control unit when to unlock the brakes. Do you want to ride a sports car with effective sensors and ABS management?
