Can You Still Drive with a Faulty ABS Sensor?

[LeJourney]

ABS sensor failure is not recommended for continued driving. When the ABS 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 for the ABS warning light staying on: Cause 1: The ABS speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting its ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed or the wheel's slip rate, thereby failing to issue appropriate commands to adjust braking. How to handle: Clean the dirt off the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal quality due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. The most common issue is a loose connection in the speed sensor wiring, which will also show as a poor speed sensor signal in the ABS computer's fault memory. How to handle: Check all wiring connections and reconnect any loose ones.
