Walker Products 350-341081 oxygen sensor for the 2018-2020 Ford F-150 V6 2.7L, 3.3L or V8 5.0L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel ratio, which supports fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Electrode coating protects against contamination and erosion from combustion residue and particulates in the exhaust gases
- Made for its specific application and fitting position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-341081 oxygen sensor
- Fits: 2018-2020 Ford F-150 V6 2.7L, 3.3L or V8 5.0L and other vehicles
- Position: Downstream, downstream left, downstream right, downstream front, downstream rear
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and newer vehicles may store a related fault code in the ECU. Those signs can have other causes. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage before you replace anything.
Fits
Fitment includes the 2020-2024 Ford Explorer V6 3.0L, which takes one sensor, and this is also an oxygen sensor for the 2018-2024 Ford Mustang V8 5.0L and the 2020-2022 Mustang V8 5.2L. This listing is a single sensor. If your vehicle isn't named here, look up your year, model and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is 350-341081 a Ford F-150 oxygen sensor for a 2018-2020 truck with the V6 2.7L, 3.3L or V8 5.0L?
Yes. Walker Products 350-341081 fits the 2018-2020 Ford F-150 V6 2.7L, V6 3.3L and V8 5.0L, with one sensor per truck.
Is this the Ford Explorer oxygen sensor for the 2020-2024 V6 3.0L?
Yes. Walker Products 350-341081 fits the 2020-2024 Ford Explorer V6 3.0L, and its position is downstream.
Is this a narrow-band or wide-band oxygen sensor?
It is narrow-band. Walker Products 350-341081 is a narrow-band sensor with a 4-wire connection.
Are the electrodes on this Walker Products oxygen sensor coated?
Yes. The electrodes are made of a gas-permeable platinum layer, and the coating protects their surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
How does this oxygen sensor affect fuel economy and emissions?
It reads the oxygen level in the exhaust so the air-fuel ratio can be fine-tuned, which supports fuel economy. It also monitors exhaust gases to help reduce pollutants.
