• Long‑Term Durability: Constructed with high‑grade materials that resist corrosion and mechanical wear, extending service life under harsh driving environments.

Technical Specifications

Installation Overview

The Metzger 0900114 is engineered for straightforward integration into the existing wheel hub assembly. The following steps outline a typical installation procedure:

1. Remove Existing Sensor: Detach the old sensor by unscrewing the mounting bolts and disconnecting the electrical connector.
2. Prepare the Hub: Clean the mounting surface to eliminate debris, ensuring a solid contact for the new sensor’s flange.
3. Mount the Sensor: Align the sensor’s mounting flange with the hub, secure it using the supplied bolts, and torque to manufacturer specifications.
4. Connect Wiring: Attach the sensor’s connector to the vehicle’s diagnostic harness, verifying correct polarity and cable integrity.
5. Test Functionality: Activate the ABS system and confirm that wheel speed data is correctly transmitted to the control unit. Use a scan tool to verify signal frequency and amplitude.

Benefits for Vehicle Performance

• Enhanced Braking Safety: Precise wheel speed detection allows the ABS module to modulate brake pressure, preventing wheel lock‑up during emergency stops.
• Improved Traction Control: Accurate data feeds into traction management systems, reducing wheel spin on slippery surfaces.
• Stability Assistance: The sensor’s reliable input supports Electronic Stability Program (ESP) algorithms, maintaining vehicle control during evasive maneuvers.
• Reduced Maintenance: Durable construction minimizes the need for frequent replacements, lowering long‑term service costs.
