Driving a car with a faulty ABS sensor can put you at risk of being in an accident. When the ABS system is not functioning correctly, it can make it difficult for the vehicle to stop quickly and safely in an emergency situation. This can increase your risk of a crash as you will not be able to slow or stop the car as quickly as you normally would. If the ABS light is illuminated, then the ABS system should be checked as soon as possible. Failing to do so can not only put you at risk of crashing, but can also damage other parts of the car such as the brakes, tires, and other related components.
