Walker 350-34299 Oxygen Sensor - Downstream Left or Downstream Right

Walker Oxygen Sensor for Jaguar Downstream Service

Walker Products 350-34299 is a heated oxygen sensor built for specific downstream applications on select Jaguar vehicles. It is engineered as an OE-style replacement to restore accurate exhaust feedback to the ECU on the affected bank and position.

For Jaguar XF, XFR, XJ8, XJR, XK, XKR, S-Type, Super V8, and Vanden Plas applications, this sensor supports proper fuel control and emissions monitoring when the original unit has aged or failed.

Key Features

• Part number: 350-34299
• Heated oxygen sensor design for faster operating temperature
• Specific-fit application for downstream left or downstream right locations
• 4-wire configuration with female radiused polygon connector
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 17.24 in.
• Overall length: 20.79 in.
• Walker Products Aftermarket engine management sensor line

Product Details

Walker Products Aftermarket develops engine management and oxygen/air-fuel sensors as OE replacement parts for worldwide vehicle coverage. This 350-34299 oxygen sensor is built for the specified fitment position so the ECU receives the correct diagnostic feedback from the exhaust stream. On affected Jaguar models, a worn downstream sensor can contribute to poor engine performance, higher fuel use, increased emissions, or a malfunction indicator light. The part number 350-34299 is listed for downstream left and downstream right locations across multiple Jaguar platforms, including 2005-2012 Jaguar XF, XFR, XJ8, XJR, XK, XKR, S-Type, Super V8, and Vanden Plas applications.

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

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect exhaust feedback to the ECU
• Rough running or reduced drivability caused by sensor degradation
• Increased fuel consumption from inaccurate air-fuel correction
• Elevated exhaust emissions from a failing oxygen sensor

Installation Notes

Verify the vehicle’s chassis or VIN breakpoints before ordering, especially on 2005-2011 Jaguar XJ8, XJR, S-Type, XF, XFR, XK, XKR, Super V8, and Vanden Plas applications. Confirm whether the vehicle requires the downstream left or downstream right position. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since damaged wiring can shorten sensor life and affect readings.

Quality Assurance

Walker Products has manufactured engine management components since 1946 and operates as an ISO 9001 / TS 16949 certified company. The 350-34299 is produced as a specific-fit replacement for the listed Jaguar applications and is intended to deliver the diagnostic feedback required by the ECU.
