What happens if the ABS sensor is broken?
1 Answers
If the ABS sensor fails, it will affect the vehicle's driving, and it is recommended not to continue driving. When the ABS warning light is on, it indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks. Common causes of the ABS warning light staying on: Cause 1: The sensing part of the ABS speed sensor is covered by mud, sludge, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt from the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal operation. Cause 2: Poor signal quality due to loose connections in the system wiring or poor contact in the ABS relay can cause system failure. The most common issue is a loose speed sensor connector, which will also show up as a speed sensor signal malfunction in the ABS computer's fault memory. Solution: Check the wiring connections and reconnect any loose parts.
