ABS braking systems are common on most new cars. ABS works to control your car's stopping power in challenging driving conditions that can make it difficult to gain traction. The system consists of valves, a controller and a speed sensor, which together provide safe braking. The function of the speed sensor is to monitor how the tires are spinning and to make sure the ABS kicks in if there is any difference or slippage between the wheels. If the sensor detects a difference, it sends a message to the controller telling it to engage the ABS, canceling manual braking.
You use your brakes every day, but the ABS rarely works. However, since your ABS speed sensor is an electronic component, it is susceptible to corrosion. You can generally expect your ABS speed sensor to travel between 30,000 and 50,000 miles - more if you don't drive often or live in an area where your car is rarely exposed to dirt, road salt, or other compounds that can cause to damage the electronics.
Signs that your ABS speed sensor needs to be replaced include:
- ABS is on
- Car slips when braking hard
- The Check Engine light comes on
- Speedometer stops working
If you think your ABS speed sensor is not working properly, you should diagnose the problem and replace the ABS speed sensor if necessary.
