Walker Products 350-34791 oxygen sensor for the 2017-2021 Jaguar F-Pace V6 3.0L, the 2019-2025 F-Pace V8 5.0L and other vehicles measures the oxygen content of the exhaust gas. Each part number is made for its specific application and fitting position, and it sends the diagnostic feedback the ECU expects.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Monitors exhaust gases and helps reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Oxygen readings help fine-tune the air-fuel mixture, which supports fuel economy
Quick facts
- Part: Walker Products 350-34791 oxygen sensor
- Fits: 2017-2021 Jaguar F-Pace V6 3.0L, the 2019-2025 F-Pace V8 5.0L and other vehicles
- Position: Center, center right, center left, downstream, downstream left

A failing sensor can show up as a rough-running engine, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is at fault, since a vacuum leak can upset the engine in a similar way. Look over the sensor's wiring harness and connector for physical damage too.
Fits
It is listed for a wide range of Jaguar and Land Rover models, including an oxygen sensor for the 2018-2025 Land Rover Range Rover Evoque 4-cylinder 2.0L and for the 2020-2025 Land Rover Defender 110 4-cylinder 2.0L, as a direct-fit replacement. If your car is not named here, look it up in the "Vehicles it fits" section to see whether this sensor is matched to it.

Frequently Asked Questions
Will this Jaguar F-Pace oxygen sensor fit a 2019-2025 F-Pace with the V8 5.0L engine?
Yes. Walker Products 350-34791 is listed for the 2017-2021 Jaguar F-Pace V6 3.0L and the 2019-2025 F-Pace V8 5.0L, with a quantity of one. For other cars, use the "Vehicles it fits" section.
Is this Walker Products oxygen sensor a narrow-band type?
Yes. The Walker Products 350-34791 is a 4-wire narrow-band oxygen sensor with a direct-fit design.
What are the electrodes of this oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. A coating on the electrode surfaces keeps combustion residue and particulates in the exhaust from contaminating or eroding them.
How does this oxygen sensor help fuel economy?
It measures oxygen levels in the exhaust so the air-fuel mixture can be fine-tuned, which helps fuel economy. It also monitors exhaust gases to help reduce pollutants.
Should I inspect the wiring when replacing this oxygen sensor?
Yes. With the engine off and cool, look over the sensor's wiring harness and connector for physical damage, which can shorten the sensor's operational life. A shop can read any stored fault codes.
