Detailed Description

The Walker Products 350-34720 oxygen sensor is designed for 2013-2015 Jaguar XF models in the downstream bank 1 sensor 2 position. As an OE-style replacement, it is built to match the application-specific fitment, mounting style, and ECU feedback requirements used by modern engine management systems. This makes it a direct choice for drivers addressing a failed downstream sensor on the Jaguar XF platform.

Walker Products Aftermarket has long focused on engine management and oxygen/air-fuel sensors for vehicle-specific applications. The 350-34720 reflects that approach with a heated sensor design, threaded installation, and connector configuration intended to align with the original vehicle setup. The part number 350-34720 is also useful when searching for a direct replacement oxygen sensor for Jaguar XF downstream service work.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Poor fuel economy caused by inaccurate exhaust feedback
• Elevated exhaust emissions from a failing sensor
• Rough engine operation tied to incorrect ECU sensor input
• Diagnostic trouble codes stored in the ECU for the affected sensor circuit

Installation Notes and Tips

Confirm the vehicle is a 2013-2015 Jaguar XF and verify the downstream bank 1 sensor 2 location before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life and affect operation. Match the threaded mounting and connector style to the original part before replacing the sensor.

For search and catalog reference, this part number is Walker 350-34720. It is also commonly searched as a Jaguar XF downstream oxygen sensor replacement and as a Walker Products 350-34720 oxygen sensor for 2013-2015 Jaguar XF.
