Mercedes Benz 1645400917 – ABS Wheel Speed Sensor is a critical sensor designed for monitoring the rotational speed of a vehicle’s wheels. This information is essential for the Anti-lock Braking System (ABS) to function properly, helping to prevent wheel lock-up during braking and maintaining vehicle stability under various road conditions.
This sensor is specifically keyed to Mercedes Benz vehicles and carries the part identifier 1645400917. When selecting a replacement, it is important to verify that the sensor matches your vehicle’s exact sensor type and part number to ensure compatibility. Buyers should compare this sensor carefully with their existing unit before purchase.
The sensor functions by sending real-time wheel speed data to the vehicle’s ABS control module. If the sensor fails or performs inconsistently, it can cause ABS warning lights to activate and negatively affect braking performance. This listing does not guarantee calibration, coding, or fault repair services, so any necessary programming may require professional attention after installation.
