Walker 350-35019 Oxygen Sensor Overview
Walker Products 350-35019 is a heated oxygen sensor built as a specific-fit OE replacement for select Mercedes-Benz, BMW, Dodge, and INFINITI applications. It is engineered to deliver the ECU feedback needed for accurate fuel control and emissions monitoring, including upstream and downstream positions where listed.
Walker Products Aftermarket focuses on application-specific engine management sensors, and this part number is matched to the vehicle position and connector style required for the listed fitments. For Mercedes-Benz G550 oxygen sensor replacement, BMW 328d after particulate filter service, or INFINITI Q50 upstream oxygen sensor service, 350-35019 is built for direct-fit installation on confirmed applications.
Key Features
- Heated oxygen sensor for faster operating temperature and signal response
- Specific-fit design for confirmed vehicle, engine, and sensor position applications
- 5-wire configuration with a 20-gauge harness
- Threaded mounting with 18.0 mm thread diameter
- Radiused polygon male connector for application-matched connection
- Wiring harness length: 19.21 in.; overall length: 22.76 in.
Detailed Product Description
Walker Products 350-35019 is an OE-style oxygen sensor designed to restore proper exhaust feedback to the ECU on supported vehicles. It is used in upstream and downstream locations depending on the application, including Mercedes-Benz GLE580, GLS580, SL550, C43 AMG, and BMW diesel models such as 328d and 535d. The sensor helps the engine management system monitor air-fuel ratio and emissions performance with the correct signal for the listed fitment.
This part cross-references Bosch 17014 and Denso 234-9005 for the same application.
What It Is Used For
- Check engine light related to oxygen sensor performance
- Rough running or poor fuel control caused by a failing sensor
- Increased fuel consumption from inaccurate exhaust feedback
- Elevated exhaust emissions from incorrect air-fuel correction
- Fault codes stored in the ECU for the affected sensor circuit
Installation Notes and Tips
- Confirm the exact year, make, model, and sensor position before ordering.
- Match the upstream, downstream, left, right, or center location shown in the fitment list.
- Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.
- Verify the threaded bung and connector orientation match the original sensor.
- Clear stored fault codes after installation and confirm proper ECU feedback with a scan tool.
Quality Assurance
Walker Products manufactures engine management and oxygen/air-fuel sensors as OE replacement parts for global vehicle applications. The brand is ISO 9001 and TS 16949 certified, with application-specific engineering and catalog support for modern vehicle fitment.
