Walker Products 250-24701 oxygen sensor for the 2004-2008 Ford F-150 V8 4.6L or 5.4L, the 2005-2008 F-150 V6 4.2L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. It is a direct-fit, 4-wire, narrow-band sensor.
- Made for a specific application and fitment position, with the diagnostic feedback the ECU requires
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels to fine-tune the air-fuel mixture for fuel economy
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24701 oxygen sensor
- Fits: 2004-2008 Ford F-150 V8 4.6L or 5.4L, the 2005-2008 F-150 V6 4.2L and other vehicles
- Position: Upstream left, upstream right, downstream left, downstream right
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. A damaged wiring harness or connector can be behind those signs too, so inspect them and find the cause before buying. If the sensor is the cause, this one replaces it.
Fits
The 1999-2001 Ford Explorer V8 5.0L, the 1999-2002 Explorer V6 4.0L, the 2001-2011 Ford Ranger V6 4.0L and the 2006-2008 Ranger V6 3.0L all fit this oxygen sensor, along with many other vehicles. Open the "Vehicles it fits" section to check your exact model and engine. This listing is one sensor, and the 2004-2008 Ford F-150 V8 4.6L takes one.

Frequently Asked Questions
Is this the right Ford F-150 oxygen sensor for a 2005-2008 model with the V6 4.2L?
Yes. Walker Products 250-24701 fits the 2005-2008 Ford F-150 V6 4.2L and the 2004-2008 F-150 V8 4.6L or 5.4L. Open the "Vehicles it fits" section to check your exact engine.
Is this the right Ford Ranger oxygen sensor for a 2006-2008 model with the V6 3.0L?
Yes. Walker Products 250-24701 fits the 2006-2008 Ford Ranger V6 3.0L and the 2001-2011 Ranger V6 4.0L.
Is this Walker Products oxygen sensor narrow-band?
Yes. This sensor is a narrow-band design with four wires and an M18 - 1.5 thread.
Can a bad oxygen sensor turn on the check engine light?
Yes. A failed sensor can trigger the malfunction indicator light, and newer vehicles may store a fault code tied to the sensor or its related systems. Rough running or higher fuel use and emissions can show up as well.
What does the coating on this oxygen sensor's electrodes do?
The coating keeps combustion residue and exhaust particulates from contaminating or eroding the electrode surfaces. The electrodes are made of a gas-permeable platinum layer.
