What does it mean to have no wheel sensor?
2 Answers
The absence of a wheel sensor indicates a malfunction in the vehicle's wheel speed sensor. Below is a detailed introduction about automotive tires: 1. Overview: Automotive tires are one of the crucial components of a vehicle, directly contacting the road surface. Together with the vehicle's suspension system, they help absorb shocks during driving, ensuring good ride comfort and smooth operation. 2. Functions: They ensure excellent adhesion between the wheels and the road surface; enhance the vehicle's traction, braking, and off-road capabilities; and bear the vehicle's weight. The significant role tires play in automobiles is increasingly being recognized.
As someone who's been driving for most of my life, I know all too well that the absence of wheel speed sensors isn't as simple as it seems. These sensors help the car monitor the rotational speed of the wheels. Without them, the entire vehicle becomes like a headless robot—the ABS anti-lock braking system becomes completely useless. For instance, when driving in rain or snow, slamming on the brakes can cause the wheels to lock up instantly, making the car prone to skidding and losing control. I've experienced this myself once and nearly had an accident. It's not just the ABS that fails; auxiliary functions like traction control also stop working, making driving both exhausting and dangerous. Of course, some older cars might not have these sensors at all to save costs or simplify design. In such cases, drivers need to be extra vigilant and manually check tire conditions regularly. My advice to everyone is to always ask the seller about the car's configuration when buying a used vehicle to avoid any unpleasant surprises.
