Walker Products 250-25119 oxygen sensor for the 2015-2017 Ford F-150 V6 3.5L or V8 5.0L and other vehicles reads the oxygen content of the exhaust gas and gives the ECU feedback on combustion. Each Walker part number is made for its specific application and fitment position on the vehicle.
- Measures oxygen levels to help fine-tune the air-fuel ratio and fuel economy
- Wide-band design that monitors the exhaust air-fuel ratio for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Quick facts
- Part: Walker Products 250-25119 oxygen sensor
- Fits: 2015-2017 Ford F-150 V6 3.5L or V8 5.0L and other vehicles
- Position: Upstream, upstream left, upstream right
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. If the sensor is the cause, this Walker Products oxygen sensor replaces it. With the engine off and cool, first look over the sensor, its wiring harness and the connector for physical damage.
Fits
The 2015-2017 Ford F-150 V6 3.5L or V8 5.0L, the 2014-2016 Ford Escape 4-cylinder 2.5L and the 2014-2016 Ford Fusion 4-cylinder 2.5L all fit this sensor, along with many other Ford models. If your Ford isn't named here, look up its year and engine in the "Vehicles it fits" section. This listing is one sensor, and the 2015-2017 Ford F-150 V6 3.5L or V8 5.0L takes one.

Frequently Asked Questions
Can I use this as a Ford F-150 oxygen sensor on a 2015-2017 F-150 with the V6 3.5L or V8 5.0L?
Yes. Walker Products 250-25119 is listed for the 2015-2017 Ford F-150 V6 3.5L or V8 5.0L, with one sensor per vehicle.
Will this work as a Ford Escape oxygen sensor on the 2014-2016 Escape 4-cylinder 2.5L?
Yes. Walker Products 250-25119 is listed for the 2014-2016 Ford Escape 4-cylinder 2.5L, which takes one sensor.
Is this oxygen sensor wide-band, and which position is it for?
Yes, Walker Products 250-25119 is a wide-band sensor. The catalog lists it for the upstream, upstream left and upstream right positions.
Will a bad wide-band oxygen sensor set a fault code?
Yes, it can. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read the stored codes.
What is the coating on this oxygen sensor for?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
