Walker Products 250-24301 oxygen sensor for the 2006-2009 Ford Fusion 4-cylinder 2.3L or V6 3.0L, the 2010 Fusion 4-cylinder 2.5L and other vehicles measures the amount of oxygen in the exhaust gas. It gives the ECU the diagnostic feedback it needs to track combustion efficiency.
- Walker Products oxygen sensor with four wires and a narrow-band design
- Electrodes made with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors the air-fuel ratio in the exhaust gas to help reduce pollutants
- Each part number is made for its specific application and its position on the vehicle
Quick facts
- Part: Walker Products 250-24301 oxygen sensor
- Fits: the 2006-2009 Ford Fusion 4-cylinder 2.3L or V6 3.0L, the 2010 Fusion 4-cylinder 2.5L and other vehicles

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 alone do not prove the sensor is the problem; a damaged wiring connector is another common cause, so look over the harness and connector for damage with the engine off.

Frequently Asked Questions
Will this Ford Fusion oxygen sensor fit a 2010 Ford Fusion 4-cylinder 2.5L?
Yes. Walker Products 250-24301 is listed for the 2006-2009 Ford Fusion 4-cylinder 2.3L or V6 3.0L and the 2010 Fusion 4-cylinder 2.5L. If your car is a different one, look it up in the "Vehicles it fits" section.
Does this Ford Taurus oxygen sensor fit a 2008-2009 Ford Taurus V6 3.5L?
Yes. Walker Products 250-24301 is listed for the 2008-2009 Ford Taurus V6 3.5L, and the fitment counts one sensor for that application.
What type of oxygen sensor is the Walker Products 250-24301?
This oxygen sensor is a narrow-band design with four wires and an M18 - 1.5 thread. Its electrodes are made with a gas-permeable platinum layer.
What does the coating on this oxygen sensor protect against?
The coating keeps combustion residue and particulates in the exhaust gases from contaminating or eroding the electrode surfaces.
What can a worn narrow-band oxygen sensor look like in everyday driving?
The engine may run poorly, fuel use or exhaust emissions may go up, or the malfunction indicator light may come on. A shop can read the stored fault codes to see which sensor or system they relate to.
