Metzger 0900473 Sensor Wheel Speed

The Metzger 0900473 is a high‑performance wheel speed sensor designed to provide precise rotational data for vehicle safety systems such as ABS, ESP, and traction control. Its robust construction and advanced magnetic sensing technology make it an ideal replacement or upgrade component for a wide range of automotive models.

Key Functionalities

• Accurate Wheel Speed Measurement: Utilizes a Hall‑effect sensor to detect the rotation of the wheel’s magnetic ring, delivering real‑time speed data to the vehicle’s control modules.
• Reliable ABS Integration: Works seamlessly with Anti‑Lock Braking Systems, ensuring optimal braking performance during emergency stops.
• ESP & Traction Control Compatibility: Provides essential input for Electronic Stability Programs and traction management systems to maintain vehicle stability under varying road conditions.
• High Durability: Encased in a rugged housing that resists vibration, temperature extremes, and corrosive environments commonly encountered on the road.

Technical Specifications

Supported Vehicle Models

The sensor is engineered to fit a broad spectrum of vehicles, particularly those from the Opel and Vauxhall families. Commonly matched models include:

• Opel Corsa D (1.0‑1.4L variants)
• Opel Corsa E
• Vauxhall Adam
• Other Opel and Vauxhall platforms that utilize the 0900473 reference part number

Because of its standardized design, the sensor can also be adapted to similar wheel hub configurations in other automotive brands with minimal modification.

Installation Overview

1. Remove Existing Sensor: Disconnect the battery, locate the wheel speed sensor on the front or rear axle, and unscrew it from the wheel hub.
2. Prepare New Sensor: Verify that the magnetic ring is clean and free of debris. If necessary, replace the ring with a compatible OEM part.
3. Mount the Sensor: Align the sensor’s mounting holes with those on the wheel hub and secure it using the supplied bolts.
4. Reconnect Wiring: Attach the sensor’s electrical connector to the vehicle’s harness, ensuring a firm connection.
5. Test Functionality: Start the engine and observe the ABS or ESP diagnostic lights. Use an OBD‑II scanner to confirm that wheel speed data is being transmitted correctly.

Performance Benefits

• Enhanced Safety: Accurate wheel speed readings reduce the likelihood of wheel lockup during braking, improving overall vehicle safety.
• Improved Stability: Reliable data for ESP systems helps maintain traction and prevent skidding on slippery surfaces.
• Long‑Term Reliability: The sensor’s durable construction minimizes maintenance needs and extends service life.

Maintenance Tips

• Inspect the magnetic ring periodically for wear or damage; replace if necessary.
• Keep the sensor housing free from oil, grease, and dirt to prevent signal interference.
• Avoid excessive vibration by ensuring all mounting bolts are tightened to manufacturer specifications.

Conclusion

The Metzger 0900473 Sensor Wheel Speed stands out as a reliable, high‑quality component for modern automotive safety systems. Its precise measurement capabilities, robust design, and compatibility with widely used vehicle models make it an excellent choice for both OEM replacements and aftermarket upgrades.
