Sensor Purpose and Function

The presented sensor is designed for installation in the rear right axle area of the vehicle. It is responsible for generating the wheel rotational speed signal, which is then sent to the ABS control unit. A properly functioning element of this type:

• supports stable braking force distribution to individual wheels,
• reduces the risk of wheel lock-up during sudden braking,
• ensures proper cooperation with related systems, such as traction control or stability control (if present in the vehicle).

Thanks to its dedicated placement on the vehicle, installation is straightforward, without the need for modifications to the wiring or interference with the suspension structure.

Compatibility with Mercedes W209

The Mercedes W209 Rear Right ABS Sensor has been developed with the specific geometry and braking system requirements of this model in mind. This means that the shape, cable length, and connector type are adapted to the factory installation, which facilitates mounting and minimizes the risk of errors. Using an original Mercedes part ensures consistency of operating parameters with other braking system components.

Performance Characteristics and Benefits

As a component in the ABS Speed Sensor category, this product is crucial for driving safety, especially in emergency braking situations or on surfaces with variable grip. Key benefits of using this sensor include:

• stable cooperation with the factory ABS control unit in the Mercedes,
• maintaining predictable braking characteristics, in line with the vehicle manufacturer's specifications,
• reducing the occurrence of errors and warning messages related to the ABS system.

The element is intended for users who expect a technically sound solution that allows for the restoration of full system functionality without experimenting with aftermarket alternatives of uncertain parameters.

Condition and Installation Aspects

The offered sensor is in used condition, allowing for an economical restoration of ABS functionality while maintaining the original manufacturer's specifications. Before installation, it is recommended to perform a standard check of the socket, wiring harness, and clean the mounting surface on the steering knuckle or hub to ensure stable seating and correct signal reading. The placement on the rear right axle is clearly defined, which facilitates the identification of the correct mounting point on the vehicle.
