Metzger 0900712 ABS Wheel Speed Sensor

The Metzger 0900712 is a high‑performance ABS wheel speed sensor designed for rear axle applications in a variety of commercial and passenger vehicles. Its compact, rugged construction delivers reliable performance under the demanding conditions typical of heavy‑duty fleets and everyday driving alike.

Key Functional Characteristics

• Precision Speed Detection: Measures wheel rotation with high accuracy to provide real‑time data for the Anti‑Lock Braking System (ABS).
• Wide Operating Temperature Range: Functions reliably from –40 °C to +120 °C, ensuring consistent performance in extreme climates.
• Robust Mechanical Design: Features a sealed housing that protects against dust, moisture, and vibration, extending service life.
• Low Power Consumption: Optimized for minimal electrical draw, reducing load on the vehicle’s power supply.
• Fast Response Time: Rapid signal generation allows the ABS controller to react instantly during braking events.

The sensor is engineered for rear‑axle wheel speed measurement in a range of models, including but not limited to:

• Citroën Jumpy II Van – rear axle
• Fiat Scudo II / Scudo II Van – rear axle
• Peugeot Expert – rear axle
• Other commercial vehicles with similar wheel speed sensor requirements

Its standardized mounting interface and electrical connections make it a drop‑in replacement for OEM units, ensuring seamless integration into existing vehicle systems.

• Signal Type: Hall effect output with a 12 V DC supply voltage.
• Current Draw: Typically around 10 mA, suitable for modern vehicle electronics.
• Connector: Standard 4‑pin or 5‑pin automotive connector, depending on the application.

• Align the sensor’s magnetic field with the wheel hub’s toothed rim for optimal signal generation.
• Secure the housing using the supplied mounting bolts; torque specifications should match OEM recommendations.
• Ensure proper grounding to avoid electrical noise that could affect ABS performance.
• Verify sensor orientation and polarity during installation to prevent misreading of wheel speed data.

After installation, the following tests confirm correct operation:

• Visual inspection for proper mounting and seal integrity.
• Electrical continuity check between sensor pins.
• Functional test using a diagnostic scan tool to read wheel speed data during vehicle movement.
• ABS system diagnostics to ensure no fault codes are triggered by the new sensor.

• Improved braking stability through accurate wheel speed feedback.
• Reduced risk of wheel lock‑up during emergency stops.
• Enhanced vehicle safety and driver confidence, especially in wet or slippery conditions.
• Longer service intervals due to the sensor’s durable construction.
