Metzger 900674 Wheel Speed Sensor

The Metzger 900674 is a high‑performance wheel speed sensor designed for automotive applications that demand precise and reliable data from the vehicle’s wheels. This sensor plays a critical role in modern braking systems, traction control, anti‑skid (ABS), electronic stability programs (ESP), and various other safety and performance modules.

Key Functionalities

• Accurate Wheel Speed Measurement: Provides real‑time data on wheel rotation speed to the vehicle’s control unit, enabling instant response in braking and stability systems.
• High Signal Integrity: Features a robust magnetic or Hall effect design that delivers clean, low‑noise signals even under harsh operating conditions such as extreme temperatures, vibration, and electrical interference.
• Compact and Durable Design: Engineered to fit within tight engine bay spaces while withstanding continuous mechanical stress and exposure to oil, coolant, and road grime.
• Wide Operating Temperature Range: Operates reliably from -40 °C to +120 °C, ensuring consistent performance in both cold climates and hot summer conditions.
• Low Power Consumption: Consumes minimal electrical power, which is essential for efficient vehicle operation and battery longevity.

Technical Specifications

Applications and Compatibility

The Metzger 900674 is widely used in commercial and passenger vehicles that require reliable wheel speed data. It is especially prevalent in:

• Renault Master Series: Front‑wheel sensors for both the standard and extended chassis variants.
• Heavy‑duty trucks, vans, and buses where durability and precision are paramount.
• High‑performance passenger cars equipped with advanced driver assistance systems (ADAS).
• Custom aftermarket builds that demand OEM‑grade sensor performance.

Installation Guidelines

1. Preparation: Ensure the vehicle’s battery is disconnected to prevent accidental electrical discharge. Clean the wheel hub area to remove dirt, oil, and debris that could interfere with sensor mounting.
2. Alignment: Position the sensor so that its magnetic or Hall element aligns precisely with the wheel speed encoder on the hub. Misalignment can lead to inaccurate readings.
3. Securing: Fasten the sensor using the supplied bolts or snap‑in mechanism, tightening to the manufacturer’s torque specifications (typically 30–40 Nm).
4. Cable Management: Route the sensor cable away from moving parts and high‑temperature zones. Use protective conduits if necessary.
5. Testing: After installation, reconnect the battery and verify that the vehicle’s diagnostic system recognizes the sensor. Perform a wheel speed test to confirm accurate signal output.

Maintenance Tips

• Inspect the sensor housing for cracks or corrosion periodically; replace if any damage is detected.
• Check cable insulation for wear and ensure connectors are tight and free of oxidation.
• Verify signal integrity using a diagnostic scan tool that can display wheel speed data in real time.
