Metzger 0900113 Wheel Speed Sensor

The Metzger 0900113 is a high‑performance wheel speed sensor designed for precision and reliability in modern automotive braking systems. It plays a crucial role in the Anti‑Lock Braking System (ABS), Electronic Stability Control (ESC), and traction control modules by accurately measuring the rotational speed of each wheel.

Key Functionalities

• Accurate Speed Detection: Utilizes a Hall effect principle to generate a precise electrical signal proportional to wheel rotation.
• Robust ABS Integration: Works seamlessly with Mercedes‑Benz models such as the C‑Class, CLK, and SLK, ensuring optimal braking performance.
• High Durability: Constructed from corrosion‑resistant materials to withstand harsh automotive environments, including temperature extremes and road debris.
• Compact Design: Small footprint allows easy installation in tight engine bay spaces without compromising sensor accuracy.

Technical Specifications

Installation Overview

Installing the Metzger 0900113 involves removing the existing wheel speed sensor and replacing it with this unit. The process typically includes:

1. Disconnecting the vehicle’s battery to ensure safety.
2. Removing the wheel hub assembly or accessing the sensor via the brake caliper.
3. Unscrewing the old sensor and carefully detaching its wiring harness.
4. Mounting the new sensor in the exact position, ensuring proper alignment with the wheel’s magnetic rotor.
5. Reconnecting the wiring harness and securing all fasteners.
6. Testing the ABS system to confirm correct sensor operation.

Performance Benefits

• Enhanced Braking Safety: Precise wheel speed data allows the ABS controller to modulate brake pressure accurately, preventing wheel lock‑up during emergency stops.
• Improved Vehicle Stability: By feeding reliable speed information to ESC modules, the sensor helps maintain vehicle control in slippery or high‑speed conditions.
• Long-Term Reliability: The robust construction reduces failure rates, ensuring consistent performance over many years of service.

Maintenance Tips

While the Metzger 0900113 is designed for minimal maintenance, periodic checks can help maintain optimal function:

• Inspect wiring connections for corrosion or damage.
• Verify sensor alignment during routine brake system inspections.
• Check for any signs of mechanical wear on the sensor housing.

Conclusion

The Metzger 0900113 Wheel Speed Sensor stands out as a reliable, high‑quality component essential for modern vehicle safety systems. Its precise speed detection, durable construction, and seamless integration with Mercedes‑Benz models make it an indispensable part of any advanced braking or stability control setup.
