Metzger 0900258 Sensor – Precision Wheel Speed Monitoring

The Metzger 0900258 Sensor is a high‑performance wheel speed detector designed for modern automotive safety systems, particularly the ABS (Anti‑Lock Braking System). It delivers reliable, accurate data on wheel rotation rates, enabling precise brake modulation and vehicle stability control.

Key Functionalities

• Hall Effect Technology: Utilizes a magnetic field to detect wheel revolutions without physical contact, ensuring durability under harsh operating conditions.
• High Accuracy: Provides precise speed measurements across the full range of vehicle speeds, from low idle to high‑speed cruising.
• Wide Temperature Range: Operates reliably between –40 °C and +120 °C, suitable for both cold climates and hot engine bay environments.
• Low Power Consumption: Designed to minimize electrical load on the vehicle’s power supply, contributing to overall system efficiency.

Compatibility & Application

The sensor is engineered for use in a variety of Ford models, including the Focus, C‑Max, and Mondeo series. It can be installed on either front or rear axles, depending on vehicle configuration. The 0900258 reference number ensures seamless integration with existing ABS modules and diagnostic systems.

Installation Overview

1. Mounting: Secure the sensor to the wheel hub using the supplied mounting bracket. Ensure alignment with the wheel’s magnetic field source.
2. Cabling: Connect the sensor’s three‑wire harness (signal, power, ground) to the vehicle’s ABS control unit. Use shielded cable to reduce electromagnetic interference.
3. Calibration: After installation, perform a quick calibration check via the vehicle’s diagnostic port to confirm correct speed readings.

Performance Highlights

• Signal Integrity: Maintains clean digital output even under high vibration and shock conditions typical of road use.
• Longevity: Designed for a service life exceeding 200,000 miles in most operating environments.
• Reliability: Proven track record in automotive safety applications, meeting stringent ISO and SAE standards.
