Walker Products 250-241185 oxygen sensor for the 2016-2019 Ford Explorer V6 3.5L and other vehicles measures the oxygen content of the exhaust gas. The ECU uses that reading to track the air-fuel ratio and combustion efficiency.
- Electrodes coated with a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports normal fuel economy
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gases
Quick facts
- Part: Walker Products 250-241185 oxygen sensor
- Fits: the 2016-2019 Ford Explorer V6 3.5L 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 or a malfunction indicator light, and each of those can have other causes. Before replacing the sensor, look over the sensor, its wiring harness and its connector for physical damage with the engine off and cool.
Fits
This sensor is listed for a wide range of Ford and Lincoln models, such as the 2017-2019 Ford Fusion V6 2.7L and the 2016-2019 Ford Taurus V6 3.5L. It is also an oxygen sensor replacement for the 2016-2019 Ford Explorer V6 3.5L, a 2016 model included. If your car is not named here, find it by model and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for the 2017-2019 Ford Fusion V6 2.7L?
Yes. Walker Products 250-241185 is listed for the 2017-2019 Ford Fusion V6 2.7L, and that engine takes one sensor. Use the "Vehicles it fits" section to look up other models.
Can I use this as the oxygen sensor for a 2016-2019 Ford Taurus V6 3.5L?
Yes. Walker Products 250-241185 is listed for the 2016-2019 Ford Taurus V6 3.5L, with one sensor per vehicle.
What thread does the 250-241185 oxygen sensor have?
This Walker Products sensor has an M18 - 1.5 thread. It is a 4-wire narrow-band oxygen sensor.
Can a bad oxygen sensor turn on the malfunction indicator light?
Yes. A failed sensor can illuminate the malfunction indicator light, and newer vehicles may store fault codes for the sensor and its related systems.
What coating does this Walker oxygen sensor have?
The electrodes are coated with a gas-permeable platinum layer. A coating also protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
