Walker Products 250-241127 oxygen sensor for the 2000-2008 Ford F-150 V8 5.4L, the 2004-2008 F-150 V8 4.6L, the 2005-2008 F-150 V6 4.2L and other vehicles measures the oxygen in the exhaust gas to monitor combustion efficiency.
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Oxygen readings help fine-tune the air-fuel mixture to support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Made for one specific position on the vehicle and gives the diagnostic feedback the ECU requires
Quick facts

A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light, but a fault elsewhere in the engine can produce those symptoms too. Before you replace it, look over the sensor, wiring harness and connector for physical damage with the engine off and cool, since damage there can shorten the sensor's life. This listing is one sensor, and the fitment calls for one.
Fits
Among the top vehicles it fits, this is an oxygen sensor for the 2001-2005 Ford Ranger V6 3.0L and the 2001-2011 Ranger 4-cylinder 2.3L, as well as for the 2004-2010 Ford Explorer V6 4.0L or V8 4.6L. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this Ford F-150 oxygen sensor right for the 2000-2008 F-150 V8 5.4L?
Yes. Walker Products 250-241127 is listed for the 2000-2008 Ford F-150 V8 5.4L, the 2004-2008 F-150 V8 4.6L and the 2005-2008 F-150 V6 4.2L. Check the "Vehicles it fits" section for your exact engine.
Is this Ford Explorer oxygen sensor right for the 2004-2010 Explorer V6 4.0L or V8 4.6L?
Yes. Walker Products 250-241127 is listed for the 2004-2010 Ford Explorer V6 4.0L or V8 4.6L.
What sensor type and thread does the 250-241127 use?
This oxygen sensor is a narrow-band type with four wires and an M18 - 1.5 thread.
What happens when an oxygen sensor like this one fails?
A failed sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or light the malfunction indicator light. Newer vehicles may also store a fault code in the ECU.
What does the coating on this oxygen sensor protect?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes use a gas-permeable platinum layer.
