Walker 350-34636 Oxygen Sensor - Downstream Left or Downstream Right

Walker 350-34636 Oxygen Sensor for Jaguar

Walker Products 350-34636 is a heated, specific-fit oxygen sensor engineered as an OE-style replacement for select Jaguar applications. It is built for downstream monitoring and provides the ECU with the feedback needed to help maintain proper fuel control and emissions performance.

Key Features

• Heated oxygen sensor for downstream exhaust monitoring
• Specific fitment for select Jaguar X-Type, S-Type, XK8, XKR, XJ8, XJR, Super V8, and Vanden Plas applications
• 4-wire design with a female radiused polygon connector
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 19.21 in.; overall length: 22.76 in.
• Walker Products Aftermarket line engineered for OE replacement fitment

Product Details

Walker Products 350-34636 is designed for downstream oxygen sensor locations on Jaguar vehicles, including downstream left, downstream right, and downstream rear positions where listed. This part number is used across multiple Jaguar platforms such as the 2002-2008 Jaguar X-Type, 2003-2005 Jaguar S-Type, 1997-2006 Jaguar XK8, 2000-2006 Jaguar XKR, 1999-2005 Jaguar Vanden Plas, 1999-2004 Jaguar XJ8 and XJR, and 2005 Jaguar Super V8. For fitment-specific applications, always match the vehicle year, model, and sensor position exactly.

Walker Products has developed its engine management and oxygen/air-fuel sensor program as an OE replacement solution for global vehicle coverage. The 350-34636 part number is built for the specified application and connector style so the ECU receives the expected diagnostic signal from the affected exhaust circuit. This part cross-references Bosch (e.g., 15717) for the same application.

Common Issues This Sensor May Address

• Check engine light or malfunction indicator light related to downstream oxygen sensor faults
• Poor fuel economy caused by inaccurate exhaust feedback
• Elevated exhaust emissions from a failing sensor signal
• Rough engine operation when the ECU receives incorrect sensor data
• Stored fault codes tied to the oxygen sensor circuit or related wiring

Installation Notes and Tips

• Confirm the exact Jaguar model, year, and sensor position before ordering.
• Inspect the sensor connector, wiring harness, and nearby exhaust wiring for heat damage or corrosion.
• Verify the chassis or VIN notes for applications such as 2005 Jaguar XJ8 and XJR, and 2006 Jaguar S-Type.
• Use the threaded mounting location specified for the vehicle and position.
• Clear diagnostic trouble codes after installation and confirm proper ECU feedback.

Quality Assurance

Walker Products has been manufacturing engine management and fuel system components since 1946 and operates with Automotive ISO9001/TS 16949 certification. The 350-34636 oxygen sensor is produced for the listed application and fitment position to support accurate diagnostic feedback in compatible Jaguar downstream sensor locations.
