Walker Products 350-34299 oxygen sensor for the 2009-2010 Jaguar XF V8 4.2L, the 2010-2011 XF V8 5.0L, the 2012 XF V6 3.0L and other vehicles reads the oxygen in the exhaust gas to gauge combustion efficiency. The Walker Products oxygen sensor is made for its specific application and fitment position, and it gives the engine computer the diagnostic feedback it expects.
- Electrodes made of a gas-permeable platinum layer
- Coating that keeps combustion residue and particulates from contaminating or eroding the electrode surfaces
- Oxygen readings that let the air-fuel mixture be fine-tuned for fuel economy
- Exhaust gas monitoring that helps reduce pollutants
Quick facts
- Part: Walker Products 350-34299 oxygen sensor
- Fits: 2009-2010 Jaguar XF V8 4.2L, the 2010-2011 XF V8 5.0L, the 2012 XF V6 3.0L and other vehicles
- Position: Downstream left, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light, though a damaged wiring harness or connector can be behind the same signs, so look those over too. This listing is one sensor, and each application takes one for the downstream left or downstream right position.
Fits
The 2009-2010 Jaguar XF V8 4.2L, the 2010-2011 XF V8 5.0L, the 2012 XF V6 3.0L, the 2010-2011 Jaguar XFR V8 5.0L and the 2005-2009 Jaguar XJ8 V8 4.2L all take this sensor, along with other Jaguar models. If your Jaguar is not named here, look up its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this Jaguar XF oxygen sensor right for the 2010-2011 XF V8 5.0L?
Yes, Walker Products 350-34299 fits the 2010-2011 Jaguar XF V8 5.0L, and the "Vehicles it fits" section covers other Jaguar years and engines.
What thread size does the Walker Products 350-34299 oxygen sensor have?
This oxygen sensor has an M18 - 1.5 thread and is a narrow-band type.
Which side does this downstream oxygen sensor go on?
Walker Products 350-34299 is catalogued for both the downstream left and downstream right positions, and each application takes one. This listing is a single sensor.
Can a bad downstream oxygen sensor turn on the malfunction indicator light?
Yes, it can, and a failed sensor can also make the engine run poorly or raise fuel consumption and exhaust emissions. Newer vehicles may store fault codes in the ECU.
What does the coating on this oxygen sensor's electrodes do?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
