Walker Products 250-24001 oxygen sensor for the 1990-1995 Ford F-150 V8 5.8L, the 1990-1996 F-150 V8 5.0L, the 1991-1994 F-150 V6 3.8L, the 1996-1997 F-150 6-cylinder 4.9L, the 1997-2003 F-150 V8 4.6L or 5.4L, the 1997-2004 F-150 V6 4.2L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns its fuel. It is made for its specific application and fitment position and returns the diagnostic feedback the ECU requires.
- Electrodes made of a gas-permeable platinum layer
- Tracks exhaust gases to help reduce pollutants for a cleaner environment
- Oxygen readings help fine-tune the air-fuel mixture, which supports fuel economy
- Coating guards the electrode surfaces against contamination and erosion by combustion residue and particulates
Quick facts
- Part: Walker Products 250-24001 oxygen sensor
- Fits: the 1990-1995 Ford F-150 V8 5.8L, the 1990-1996 F-150 V8 5.0L, the 1991-1994 F-150 V6 3.8L, the 1996-1997 F-150 6-cylinder 4.9L, the 1997-2003 F-150 V8 4.6L or 5.4L, the 1997-2004 F-150 V6 4.2L and other vehicles
- Condition: New
A failing oxygen sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. Those signs can come from other faults too, so with the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage, and find the cause before you replace the sensor.
Fits
This oxygen sensor is listed for a wide range of Ford, Lincoln, Mercury and Mazda models. Besides the F-150 above, it fits the 1995-2010 Ford Explorer V6 4.0L, the 1996-2001 Explorer V8 5.0L and the 2002-2010 Explorer V8 4.6L, and it is an oxygen sensor for the 2005-2008 Ford Escape 4-cylinder 2.3L, the 2009-2010 Escape 4-cylinder 2.5L and the 2010 Escape V6 3.0L. The fitment gives a quantity of one per application, and this listing is one sensor.

Frequently Asked Questions
Is this the right oxygen sensor for a 1997-2003 Ford F-150 V8 4.6L or 5.4L?
Yes. Walker Products 250-24001 is listed for the 1997-2003 Ford F-150 V8 4.6L or 5.4L. For another year or engine, enter your vehicle in the "Vehicles it fits" section and see whether this number comes up.
Is this an oxygen sensor for the 2002-2010 Ford Explorer V8 4.6L?
Yes. Walker Products 250-24001 is listed for the 2002-2010 Ford Explorer V8 4.6L, and the fitment calls for a quantity of one.
Is the Walker Products 250-24001 a narrow-band or wideband sensor?
This sensor is a narrow-band type with four wires and an M18 - 1.5 thread, made as a direct-fit part.
Can a failing oxygen sensor store a fault code?
Yes, it can on newer vehicles. Fault codes are stored in the ECU, and some relate to the affected sensor and its associated systems. A shop can read them.
What are the electrodes of the Walker Products 250-24001 oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer, and a coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
