Metzger 900670 Wheel Speed Sensor

The Metzger 900670 is a high‑performance wheel speed sensor designed for automotive safety systems such as ABS, traction control, and electronic stability programs. It employs a Hall‑effect principle to accurately detect the rotational speed of a vehicle’s front wheels, ensuring reliable braking performance under all driving conditions.

Core Technology

The sensor incorporates a Hall‑effect transducer that converts magnetic field variations into electrical signals. When the wheel turns, the rotating toothed wheel (or gear) passes by the sensor, creating a series of magnetic pulses. The Hall element detects these pulses and outputs a square wave whose frequency is directly proportional to wheel speed.

Key advantages:

• High accuracy: Maintains precise speed measurement even at high RPMs.
• Robust construction: Resistant to vibration, temperature extremes, and moisture.
• Low power consumption: Ideal for modern vehicle electrical architectures.
• Compact size: Fits seamlessly into existing wheel hub assemblies.

Compatibility Overview

The Metzger 900670 is engineered to fit a wide range of front‑wheel vehicles, particularly those from the French and European markets. It serves as an original equipment replacement for models such as:

• CITROËN C3 (single & multi‑door)
• CITROËN C2
• PEUGEOT 1007
• Other front‑wheel vehicles that use the same wheel hub geometry and ABS architecture.

Its universal mounting design allows technicians to swap it into any compatible hub without extensive modifications. The sensor’s electrical interface matches standard automotive wiring harnesses, ensuring plug‑and‑play installation.

Installation Guide

1. Safety first: Raise the vehicle and secure it on jack stands. Disconnect the battery to prevent accidental short circuits.
2. Remove the wheel: Use a lug wrench or impact gun to detach the front wheel, exposing the hub assembly.
3. Detach the old sensor: Locate the existing wheel speed sensor on the hub. Carefully disconnect its wiring connector and unscrew the mounting bolt.
4. Mount the new sensor: Align the Metzger 900670 with the hub’s magnetic gear. Secure it using the supplied mounting bolt, ensuring a tight fit to avoid signal loss.
5. Reconnect wiring: Plug the sensor’s connector into the vehicle’s harness. Verify that all pins are correctly seated.
6. Reinstall the wheel: Tighten lug nuts in a star pattern, lower the car, and perform a final torque check.
7. Test functionality: Start the engine and observe the ABS light. If it remains off or turns off after a brief period, the sensor is functioning correctly.

Maintenance Tips

• Inspect the sensor connector for corrosion; clean with electrical contact cleaner if necessary.
• Avoid exposing the sensor to excessive moisture or oil. Use a protective cover during long storage periods.
• If the ABS system shows irregular behavior, consider checking the sensor’s signal output with a diagnostic scan tool.
