Metzger 0900087 Sensor – Precision Wheel Speed Measurement

The Metzger 0900087 Sensor is a high‑performance wheel speed detector designed for the rear axle of modern vehicles such as Ford, Volkswagen, Seat, and others. It plays a critical role in vehicle safety systems by providing accurate rotational data to the Anti‑Lock Braking System (ABS) and Electronic Stability Control (ESC).

Key Functionalities

• Inductive Wheel Speed Sensing: Utilizes an inductive pickup coil that detects changes in magnetic flux as the wheel rotates, ensuring reliable operation even under harsh environmental conditions.
• ABS Integration: Delivers precise speed signals to the ABS control unit, enabling timely brake modulation and preventing wheel lock‑up during emergency stops.
• Compatibility with Rear Axle Systems: Specifically engineered for the rear right side of vehicles such as Ford Galaxy, Seat Alhambra, and Volkswagen Sharan.
• Robust Construction: Encased in a durable housing that protects against moisture, dust, and mechanical shock, extending service life under demanding road conditions.

Installation Guidelines

1. Safety First: Ensure the vehicle is securely lifted and supported before removing the existing wheel speed sensor.
2. Remove Old Sensor: Disconnect the electrical connector, unscrew the mounting bolt, and carefully detach the sensor from the axle shaft.
3. Prepare New Sensor: Verify that the sensor’s magnetic pole aligns correctly with the wheel hub. Apply a thin layer of anti‑seize compound to the mounting surface if recommended by the manufacturer.
4. Mounting: Secure the Metzger 0900087 onto the axle using the supplied bolt, ensuring tight torque specifications are met.
5. Reconnect Wiring: Attach the sensor’s connector to the vehicle’s wiring harness, checking for proper polarity and secure contact.
6. Testing: After installation, run a diagnostic scan to confirm that wheel speed signals are being correctly transmitted to the ABS module.

Performance Benefits

• Enhanced Safety: Reliable wheel speed data reduces the risk of brake lock‑up and improves overall vehicle stability during sudden deceleration.
• Long-Term Reliability: The sensor’s robust design minimizes maintenance needs, providing consistent performance over thousands of miles.
• Seamless Integration: Designed to fit standard mounting points on compatible vehicles, eliminating the need for custom adapters or extensive modifications.

Maintenance Tips

• Inspect the sensor housing and connector periodically for signs of corrosion or damage.
• Keep the sensor area clean; debris can interfere with magnetic flux detection.
• Replace the sensor if diagnostic codes indicate irregular wheel speed readings or ABS malfunction.

Conclusion

The Metzger 0900087 Sensor exemplifies precision engineering in automotive safety components. Its inductive design, robust construction, and dedicated compatibility with rear axle systems make it an essential part of modern vehicle braking and stability control architectures.
