Walker Products 250-241247 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. This Walker Products oxygen sensor monitors the air-fuel ratio for combustion efficiency.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
- Electrodes with a gas-permeable platinum layer
- Narrow-band sensor with four wires
- Made for its specific application and fitment position
- Gives the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-241247 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 oxygen sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. Those signs alone do not prove the sensor is at fault, because an exhaust leak can cause similar symptoms. The sensor, wiring harness and connector should also be checked for physical damage.
Fits
This direct-fit oxygen sensor also fits the 2020-2024 Ford Explorer V6 3.0L, the 2018-2023 Ford Mustang V8 5.0L and the 2020-2022 Mustang V8 5.2L. This listing is one sensor, and the 2020-2024 Ford Explorer V6 3.0L takes one. If your car is not named here, open the "Vehicles it fits" section and look up your exact model and engine.

Frequently Asked Questions
Is this Ford F-150 oxygen sensor right for a 2018-2020 F-150 with the V6 2.7L, 3.3L or V8 5.0L?
Yes. Walker Products 250-241247 is listed for the 2018-2020 Ford F-150 V6 2.7L, V6 3.3L and V8 5.0L, and each of those takes one sensor.
Is the Walker Products 250-241247 a narrow-band or wideband sensor?
Walker Products 250-241247 is a narrow-band, direct-fit sensor with four wires and an M18 - 1.5 thread.
What is the coating on this oxygen sensor for?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gas. The electrodes have a gas-permeable platinum layer.
What can a failing downstream oxygen sensor cause?
A failing sensor can make the engine run poorly, increase fuel consumption and exhaust emissions, or light the malfunction indicator light. Newer vehicles may also store a fault code in the ECU.
Does this oxygen sensor send feedback to the ECU?
Yes. Walker Products 250-241247 is made for its specific application and fitment position, and it gives the diagnostic feedback the ECU requires.
