Is it a problem to continue driving with a faulty wheel speed sensor?
1 Answers
There is indeed a problem. Once the wheel speed sensor is damaged, it not only causes a certain deviation in the speed display on the dashboard but also leads to unstable engine idling and reduced acceleration performance. Additionally, when the vehicle starts or decelerates to a stop while driving, it is prone to sudden pauses and may even stall directly, which significantly affects driving safety to some extent. Classification of wheel speed sensors: Magnetic wheel speed sensors: Designed based on the principle of electromagnetic induction, they feature a simple structure, low cost, and resistance to mud and dirt, making them widely used in modern car ABS anti-lock braking systems. Hall-effect wheel speed sensors: Made using the Hall effect principle, these sensors are also widely applied in vehicles. They are characterized by output signal voltage amplitude not being affected by rotational speed, high-frequency response, and strong resistance to electromagnetic interference.
