Walker Products Oxygen Sensor P/N:350-341095
Walker 350-34662 oxygen sensor for the 2019-2020 Volvo S90 4-cylinder 2.0L and other vehicles measures the oxygen content of the exhaust gas. This Walker oxygen sensor is a downstream unit made for its specific application and fitment position, and it sends the ECU the diagnostic feedback it needs.
A failing oxygen sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. A damaged wiring harness or connector can produce the same signs, so look both over for physical damage with the engine off and cool before you replace the sensor.
It is an oxygen sensor for a wide range of Volvo and Polestar models, led by the 2016-2020 Volvo XC90 4-cylinder 2.0L and the 2022-2025 Volvo XC60 4-cylinder 2.0L. If your car is not named here, look for its year and engine on the Buyer's Guide tab. This listing is one sensor, and the 2019-2020 Volvo S90 4-cylinder 2.0L takes one.
Fit and size
Build and materials
Is this oxygen sensor for the 2016-2020 Volvo XC90 4-cylinder 2.0L?
Yes. Walker 350-34662 is listed for the 2016-2020 Volvo XC90 4-cylinder 2.0L as a downstream sensor, and that car takes one.
Is the Walker Products oxygen sensor 350-34662 an upstream or downstream sensor?
It is a downstream sensor. Walker 350-34662 is made for its specific application and fitment position on the vehicle.
What type of sensor is this Walker O2 sensor, and what thread does it have?
It is a narrow-band sensor with an M18 - 1.5 thread. It measures the oxygen content of the exhaust gas to track the air-fuel ratio.
What can a failing downstream oxygen sensor do to fuel use and emissions?
It can raise fuel consumption and exhaust emissions, make the engine run poorly or light the malfunction indicator light. Newer vehicles store fault codes in the ECU, and a shop can read them.
What protects the electrodes on this oxygen sensor?
A coating on the electrode surfaces guards against contamination and erosion from combustion residue and particulates in the exhaust. The electrodes also carry a gas-permeable platinum layer.
