Walker Products 250-24989 oxygen sensor for the 2011-2014 Ford F-150 V6 3.7L, the 2011-2017 F-150 V6 3.5L, the 2015-2017 F-150 V6 2.7L or V8 5.0L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. This 4-wire, direct-fit, narrow-band Walker Products oxygen sensor reports the air-fuel ratio back to the engine computer.
- Made for its specific application and fitment position, with the diagnostic feedback the ECU needs
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Monitors the exhaust gases to support lower emissions
- Electrodes use a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24989 oxygen sensor
- Fits: the 2011-2014 Ford F-150 V6 3.7L, the 2011-2017 F-150 V6 3.5L, the 2015-2017 F-150 V6 2.7L 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 use, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can be behind these symptoms too, as can other faults in the engine or exhaust, so track down the cause before you buy a sensor. With the engine off and cool, you can look over the sensor, harness and connector for physical damage.
Fits
This oxygen sensor is listed for a wide range of Ford, Lincoln and Mercury models. It works as an oxygen sensor for the 2013-2015 Ford Explorer V6 3.5L and for the 2011-2012 Ford Escape V6 3.0L and the 2012 Escape 4-cylinder 2.5L. If your own vehicle is not named here, look it up in the "Vehicles it fits" section before you order. This listing is one sensor; most listed engines take one, and the 2011-2014 Ford F-150 V6 3.7L takes two.

Frequently Asked Questions
Is this the right Ford F-150 oxygen sensor for a 2011-2014 F-150 V6 3.7L?
Yes. Walker Products 250-24989 is listed for the 2011-2014 Ford F-150 V6 3.7L, which takes two sensors. The 2011-2017 F-150 V6 3.5L takes one.
What type of oxygen sensor is the Walker Products 250-24989?
Walker Products 250-24989 is a 4-wire, direct-fit, narrow-band oxygen sensor with M18 - 1.5 threads.
Which symptoms can point to a failing downstream oxygen sensor?
Rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can be signs of a failed sensor. Newer vehicles also store fault codes, and some relate to the affected sensor.
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 themselves use a gas-permeable platinum layer.
Is the Walker Products 250-24989 an upstream or downstream oxygen sensor?
It is a downstream sensor. The catalog lists it for downstream positions, including downstream left, right, front and rear.
