Walker 350-64046 Oxygen Sensor - Upstream Left, Upstream Rear or Upstream Right

Walker 350-64046 Oxygen Sensor for Jaguar

Walker Products 350-64046 is a heated, specific-fit oxygen sensor engineered as an OE-style replacement for select Jaguar applications. It is built for upstream locations and supports accurate ECU feedback for air-fuel control, emissions monitoring, and drivability.

For Jaguar X-Type, S-Type, XJ8, XJR, XK8, XKR, Vanden Plas, and Super V8 applications, this Walker Products Aftermarket sensor is matched to the vehicle’s fitment position and connector style for direct replacement service.

Product Details

Walker Products develops engine management and oxygen/air-fuel sensors as OE replacement parts for worldwide vehicle coverage. Part number 350-64046 is designed for the specified upstream positions and provides the diagnostic feedback the ECU expects from the sensor circuit. This matters on Jaguar X-Type and Jaguar S-Type models, as well as XJ8, XJR, XK8, XKR, Vanden Plas, and Super V8 vehicles where upstream sensor performance directly affects fuel control and emissions monitoring. This part cross-references Bosch (e.g., 15717) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough running caused by incorrect air-fuel feedback
• Increased fuel consumption from a failing upstream sensor
• Higher exhaust emissions from inaccurate sensor readings
• Fault codes stored in the ECU for sensor circuit issues

Installation Notes

Confirm the exact year, model, and upstream left, upstream right, or upstream rear position before ordering. For 2006 Jaguar S-Type applications, verify chassis number N52047. For 2005 Jaguar XJ8 and XJR applications, verify chassis/VIN G49700. Inspect the sensor, wiring harness, and connector for physical damage before installation, since damaged components can shorten service life.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and operates as an ISO 9001/TS 16949 certified company. The 350-64046 oxygen sensor is built to support the diagnostic and emissions requirements of the listed Jaguar fitments.
