Is it a problem to continue driving with a faulty wheel speed sensor?

[StBentley]

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.

Continuing to drive with a faulty wheel speed sensor is absolutely a risky behavior. I know some people think the car can still run and there's no major issue, but this is a serious safety hazard. It is primarily responsible for measuring wheel speed and controlling the ABS and traction systems. If it fails, the ABS may not function, making the tires prone to locking up during rainy weather or sudden braking, leading to skidding or even loss of control. I've experienced a similar situation before—when braking on the highway, I felt the car wobble, which gave me a cold sweat. Driving long-term with it broken can also affect other electronic systems, such as stability control failure and constant dashboard warning lights. The risk skyrockets, especially in bad weather. I don't recommend pushing through; it's better to spend some money to fix it and ensure safe travel. If you must drive, choose low-speed, short-distance trips and avoid highways or congested areas to reduce sudden accidents.
