Walker 350-34160 Oxygen Sensor - Downstream, Downstream Right or Upstream

Walker 350-34160 Oxygen Sensor for Volkswagen

Walker Products 350-34160 is a heated oxygen sensor built as an OE-style replacement for specific Volkswagen applications. It is engineered for the correct fitment position and ECU feedback on supported vehicles, including Volkswagen Beetle, Jetta, Passat, EuroVan, Cabrio, and Touareg models.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for direct replacement use. The 350-34160 follows the application-specific approach needed for upstream and downstream service on select Volkswagen vehicles.

Key Features

• Heated oxygen sensor for emissions and fuel-control feedback
• Specific fit design for the listed Volkswagen applications
• Threaded mounting type with 18.0 mm thread diameter
• 4-wire configuration with 22-gauge wiring
• Radiused polygon male connector for vehicle-specific connection
• Wiring harness length: 46.77 in.; overall length: 50.31 in.
• Fits upstream, downstream, and downstream right positions depending on application

Detailed Description

The Walker 350-34160 oxygen sensor is designed to replace the original sensor on select Volkswagen models where accurate exhaust-gas feedback is required by the ECU. As a heated sensor, it helps the engine management system monitor air-fuel conditions during operation and supports proper emissions control. This part number is listed for 2000-2011 Volkswagen applications, including Beetle, Jetta, Passat, EuroVan, Cabrio, and Touareg, with fitment varying by engine and sensor position. For Volkswagen Beetle oxygen sensor replacement or a Volkswagen Jetta upstream oxygen sensor, confirm the exact engine code and sensor location before installation. This part number, 350-34160, is built for specific applications rather than universal use.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light or malfunction indicator light related to oxygen sensor faults
• Poor engine performance caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel monitoring
• Higher exhaust emissions from a failing upstream or downstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Verify the vehicle year, model, engine code, and sensor position before ordering. This Walker oxygen sensor uses a threaded mount and vehicle-specific connector, so the existing harness and connector should be inspected for damage before installation. On affected Volkswagen Beetle, Jetta, Passat, EuroVan, Cabrio, and Touareg vehicles, confirm whether the application calls for upstream, downstream, or downstream right placement. If the sensor wiring or connector shows heat damage, corrosion, or abrasion, address those issues during service to avoid shortened sensor life.

Quality Assurance

Walker Products has manufactured engine management and oxygen/air-fuel sensors as OE-replacement parts for many vehicle applications worldwide since 1946. The company is Automotive ISO9001/TS 16949 certified, and this part is produced for the specified application and ECU feedback requirements.
