Bosch 0 265 009 271 ABS Wheel Speed Sensor

Bosch 0 265 009 271 ABS Wheel Speed Sensor is a precision‑engineered component designed to monitor the rotational velocity of a vehicle’s rear wheel. This sensor plays a pivotal role in the Anti‑Lock Braking System (ABS), ensuring that each wheel maintains optimal traction during braking, thereby enhancing safety and stability.

Core Functionality

The sensor operates on the Hall effect principle. As the wheel turns, a magnetic field generated by the rotor interacts with the Hall element inside the sensor. This interaction produces an electrical signal proportional to the wheel’s speed. The vehicle’s electronic control unit (ECU) receives this signal and calculates braking force distribution across all wheels.

Key Technical Specifications

• Model Number: 0 265 009 271
• Application: Rear wheel speed sensor for Ford models such as the Fiesta, Ecosport, and other compatible vehicles.
• Sensor Type: Hall effect magnetic sensor.
• Signal Output: Digital pulse train (typically 5 V DC).
• Operating Temperature Range: –40 °C to +125 °C.
• Dimensions: Compact design for tight mounting spaces.
• Connector Type: Standard automotive plug compatible with OEM wiring harnesses.

Installation and Compatibility

The sensor is engineered to fit seamlessly into the rear wheel assembly of a wide range of Ford vehicles. It is available in both left‑side (driver) and right‑side (passenger) variants, ensuring full compatibility with models such as:

• Ford Fiesta Mk6 (2013–2020)
• Ford Ecosport (2014–2022)
• Ford Figo III
• Other Ford vehicles equipped with a rear‑wheel ABS module.

Installation typically involves removing the wheel, accessing the sensor housing, and connecting the sensor to the vehicle’s wiring harness. The sensor’s robust construction guarantees reliable performance even under harsh driving conditions.

Performance Benefits

• Enhanced Braking Efficiency: Accurate wheel speed data allows the ABS system to modulate brake pressure, preventing wheel lock‑up and maintaining steering control during emergency stops.
• Improved Vehicle Stability: By monitoring each wheel independently, the sensor contributes to traction control (TCS) and electronic stability program (ESP) functions.
• Long‑Term Reliability: Bosch’s stringent quality controls ensure that the sensor withstands vibration, temperature extremes, and exposure to road salts and debris.

Maintenance Tips

While the sensor is designed for low maintenance, periodic checks can help maintain optimal performance:

• Inspect the wiring harness for signs of wear or corrosion.
• Ensure that the sensor housing remains free from dirt and debris.
• Verify that the sensor connector is securely fastened to prevent intermittent signals.
