Walker 350-34486 Oxygen Sensor for Jaguar and Volvo

Walker Products 350-34486 is a heated, threaded oxygen sensor built as a specific-fit OE replacement for select Jaguar and Volvo applications. It is engineered to deliver the diagnostic feedback the ECU expects, helping maintain proper fuel control and emissions performance.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct application matching
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for vehicle-specific connection
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 32.01 in.; overall length: 35.55 in.

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered for OE-style replacement use. Part number 350-34486 is designed for downstream placement on supported vehicles, including Jaguar XK, XKR, XKR-S, XF, XFR, XJ, and Volvo XC90, S80, V70, S40, S60, and V50 applications. For buyers searching for a downstream oxygen sensor for a 2010-2015 Jaguar XK or a downstream oxygen sensor for a 2005-2011 Volvo XC90, this sensor matches the listed position and connector style for the specified vehicles.

This part cross-references no listed interchange numbers in the provided data.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by incorrect exhaust feedback
• Rough engine operation from inaccurate air-fuel readings
• Elevated exhaust emissions from a failing downstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Verify the exact vehicle, model year, and downstream position before ordering. Confirm connector shape, wire count, and thread diameter against the original sensor. Inspect the sensor harness and connector for heat damage, abrasion, or corrosion before installation, since physical damage can shorten service life and affect signal quality. For 2011 Jaguar XF and XFR applications, confirm the chassis/VIN break noted in the fitment data.

Quality Assurance

Walker Products has manufactured engine management components since 1946 and operates as an ISO 9001/TS 16949 certified company. This oxygen sensor is built to support the diagnostic feedback required by the ECU on the listed Jaguar and Volvo applications.
