Installation & Maintenance

1. Preparation: Warm up the engine to operating temperature. This ensures accurate sensor readings during installation.
2. Removal: Disconnect the electrical connector, then unscrew the sensor housing using a suitable socket or wrench. Carefully remove the old sensor without damaging the exhaust manifold.
3. Installation: Position the new Metzger 0893081 Lambda Sensor onto the exhaust pipe, aligning the M18x1.5 screw holes. Tighten securely to avoid leaks.
4. Reconnection: Reattach the electrical connector and verify that all connections are firm.
5. Testing: Start the engine and monitor ECU diagnostics for lambda sensor status. A stable voltage output indicates correct installation.

Routine maintenance is minimal; however, inspect the sensor housing for cracks or corrosion after extended use in harsh environments. Replace if any damage is detected to maintain optimal performance.
