Detailed Description

Walker Products 350-34069 is an oxygen sensor for Mercedes-Benz G63 AMG models that require a downstream replacement on either side. As a heated sensor, it is designed to provide the ECU with the feedback needed for emissions system monitoring and fault detection. The specific-fit design helps match the original mounting position, connector style, and wiring layout used on the vehicle.

This part number, 350-34069, is intended for 2013-2014 Mercedes-Benz G63 AMG applications and is a direct replacement choice when diagnosing a failed downstream sensor. If the sensor circuit is compromised, the vehicle may store fault codes, run less efficiently, increase fuel consumption, or trigger the malfunction indicator light. The part number 350-34069 is built to address those downstream oxygen sensor service needs with application-specific fitment.

What It Helps Address

• Stored oxygen sensor or emissions-related fault codes
• Illuminated malfunction indicator light from a failed downstream sensor
• Poor engine operation caused by inaccurate exhaust feedback
• Increased fuel consumption linked to sensor signal issues
• Higher exhaust emissions from a degraded oxygen sensor

Installation Notes and Tips

Before installation, inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion. Confirm the downstream position on the right or left side before ordering, since this application is position-specific. Verify the threaded mounting location and connector orientation against the original sensor to ensure proper installation on the Mercedes-Benz G63 AMG.
