Walker Products 250-25169 oxygen sensor for the 2011-2014 Ford F-150 V6 3.7L and other vehicles measures combustion efficiency from the amount of oxygen in the exhaust gas. This Walker Products oxygen sensor gives the ECU the diagnostic feedback it requires.
- Manufactured for its specific application and fitment position
- 5-W wide-band oxygen sensor design
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
- Monitors the air-fuel ratio and helps fine-tune the air-fuel mixture
Quick facts
- Part: Walker Products 250-25169 oxygen sensor
- Fits: 2011-2014 Ford F-150 V6 3.7L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, though those signs have other causes too. Before you replace it, rule out physical damage to the wiring harness and connector, which should be checked along with the sensor. Newer vehicles store fault codes in the ECU, and some relate to this sensor.
Fits
The 2011-2014 Ford F-150 V6 3.7L, 2012-2015 Ford Explorer V6 3.5L and 2013-2015 Ford Taurus V6 3.5L are among the vehicles this oxygen sensor fits, along with many others. This listing is one sensor.

Frequently Asked Questions
Is this an oxygen sensor for the 2011-2014 Ford F-150 V6 3.7L?
Yes, Walker Products 250-25169 fits the 2011-2014 Ford F-150 V6 3.7L, which takes two; this listing is one sensor.
Is this an oxygen sensor for the 2012-2015 Ford Explorer V6 3.5L?
Yes, Walker Products 250-25169 fits the 2012-2015 Ford Explorer V6 3.5L, which takes one; for any other vehicle, look up your year, model and engine in the "Vehicles it fits" section.
What sensor type and thread size does this 5-W wide-band oxygen sensor have?
This oxygen sensor is a 5-W wide-band type with an M18 - 1.5 thread. Its position is listed as upstream.
What signs can point to a failing wide-band oxygen sensor?
Rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can come from a failed sensor, and from other faults as well.
What does the electrode coating on this oxygen sensor do?
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.
