- Test drive the vehicle to monitor for warning lights and confirm accurate speedometer readings.
Understanding the Wheel Speed Sensor Function
The wheel speed sensor tracks how fast each wheel spins. This is key for keeping your Hyundai Sonata stable and safe. It helps the anti-lock braking system (ABS) and electronic stability control (ESC) work properly.
The wheel speed sensor is essential for your Hyundai Sonata's stability, aiding in ABS and ESC functionality for safe driving.
When one wheel spins faster, ABS kicks in. This prevents the wheels from locking up and helps maintain traction, especially during sudden stops. The ESC also uses wheel speed data to help you steer safely in sharp turns or bad weather.
Each wheel has its own sensor for accurate readings and quick adjustments. If a sensor fails, you may see warning lights or notice handling issues.
Regular checks can help keep your Sonata safe and responsive on the road.
