Metzger 0900679 Sensor Wheel Speed

The Metzger 0900679 is a high‑performance wheel speed sensor specifically engineered for the Mazda 6 series, including hatchback and station wagon variants produced between 2002 and 2007. This component plays a pivotal role in the vehicle’s safety systems, feeding real‑time data to the Anti‑Lock Braking System (ABS), Electronic Stability Program (ESP), and traction control modules.

Key Functionalities

• Accurate Speed Measurement: Utilizes magnetic induction to detect wheel rotation with exceptional precision, ensuring reliable braking performance even under extreme driving conditions.
• ABS Integration: Provides critical input for the ABS control unit, enabling rapid modulation of brake pressure during lock‑up scenarios and preventing loss of vehicle control.
• ESP & Traction Control Support: Supplies wheel speed data to stability management systems, allowing them to detect skids or oversteer events and apply corrective braking forces.
• High Durability: Constructed from corrosion‑resistant materials and sealed against dust, water, and temperature fluctuations typical of automotive environments.

Design & Construction

The sensor features a robust sealed housing that protects the internal magnetic core and electronic circuitry. Its compact dimensions allow seamless installation in the front left wheel assembly without requiring modifications to existing brackets or mounts. The sensor’s output is a standard Hall‑effect signal, compatible with Mazda’s proprietary ABS control architecture.

Installation Overview

1. Remove the Wheel: Safely lift the vehicle and detach the front left wheel to access the hub assembly.
2. Detach the Existing Sensor: Unscrew the old wheel speed sensor, noting its orientation for correct placement of the new unit.
3. Mount the Metzger 0900679: Align the sensor’s magnetic core with the wheel’s rotating disc or gear and secure it using the supplied mounting hardware.
4. Reconnect Wiring Harness: Attach the sensor’s connector to the vehicle’s ABS harness, ensuring a firm connection to avoid intermittent faults.
5. Test Functionality: After reassembly, start the engine and verify that the ABS light remains off. A diagnostic scan can confirm proper sensor operation.
