Walker OE Replacement Oxygen Sensor 350-34352
Walker OE Replacement oxygen sensor 350-34352 is a direct-fit heated sensor built for specific vehicle applications and ECU feedback requirements. It is engineered for downstream use on select Audi TT and TTS Quattro models, including 2014 Audi TTS Quattro downstream and 2009-2011 Audi TTS Quattro downstream.
Key Features
- Heated oxygen sensor for precise exhaust monitoring
- Specific-fit design for the listed Audi applications
- 4-wire configuration with 22-gauge wiring
- 43.82 wiring harness length and 47.36 overall length
- 18.0 mm threaded mounting design
- Radiused polygon male connector for vehicle-specific connection
Product Details
Walker Products OE Replacement sensors are developed as original-equipment-style replacements for engine management systems that rely on accurate oxygen sensor input. Part number 350-34352 is built for the correct fitment position and diagnostic feedback expected by the ECU, making it a practical choice for downstream oxygen sensor service on Audi TT Quattro and Audi TTS Quattro applications. This part cross-references Bosch 17098 for the same application.
Compatible With 2014 Audi TTS Quattro, downstream; 2009-2011 Audi TTS Quattro, downstream; and 2008-2009 Audi TT Quattro, downstream right. Walker 350-34352 is a fitment-specific replacement for drivers addressing sensor-related fault codes on these vehicles.
Common Reasons for Replacement
- Check engine or malfunction indicator light related to oxygen sensor performance
- Poor engine operation caused by incorrect exhaust feedback
- Increased fuel consumption from inaccurate air-fuel monitoring
- Higher exhaust emissions from a failing downstream sensor
- Stored ECU fault codes tied to the sensor, wiring, or connector
Installation Notes
Verify the downstream position before installation and inspect the sensor wiring harness and connector for damage. Confirm thread size, connector shape, and harness length against the original part before service. Because this is a specific-fit sensor, correct vehicle application matching is important for proper ECU communication.
Quality Assurance
Walker Products manufactures engine management and oxygen/air-fuel sensors as OE replacement components and operates as an ISO 9001/TS 16949 certified company. Since 1946, the brand has focused on sensor and fuel system components for vehicle repair and maintenance.
