Walker Products 350-34316 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 reads the oxygen in the exhaust gas so the ECU can judge combustion efficiency. It is a direct-fit, narrow-band sensor made for its specific application.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Oxygen readings help fine-tune the air-fuel mixture and support fuel economy
- Electrodes made of a gas-permeable platinum layer
- Exhaust gas monitoring that supports emissions control
- Built for its specific application, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-34316 oxygen sensor
- Fits: 2006-2009 Ford Fusion 4-cylinder 2.3L or V6 3.0L, the 2010 Fusion 4-cylinder 2.5L and other vehicles
- Position: upstream, downstream, upstream left, upstream right, upstream rear, upstream front
- Condition: New
A worn sensor can show up as rough running, higher fuel use or a lit malfunction indicator light, and newer vehicles may store a fault code. Those symptoms alone don't point to the sensor, because damage to the wiring harness or connector can produce them too. This listing is one sensor for one position; a sensor at another position is ordered separately.
Fits
This sensor is listed for a wide range of Ford, Lincoln, Mazda and Mercury models, among them the 2005-2008 Ford Escape 4-cylinder 2.3L and the 2009 Escape 4-cylinder 2.5L or V6 3.0L, and the 2008-2009 Ford Taurus V6 3.5L. If your car isn't named here, look up its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right Ford Fusion oxygen sensor for a 2006-2009 4-cylinder 2.3L or V6 3.0L, or a 2010 4-cylinder 2.5L?
Yes. Walker Products 350-34316 is listed for the 2006-2009 Ford Fusion with the 4-cylinder 2.3L or V6 3.0L and for the 2010 Fusion with the 4-cylinder 2.5L.
Is this Ford Taurus oxygen sensor right for a 2008-2009 V6 3.5L?
Yes, it is listed for the 2008-2009 Ford Taurus V6 3.5L. For any other model, check your year and engine in the "Vehicles it fits" section.
Is the Walker Products 350-34316 a narrow-band sensor?
Yes. Walker Products 350-34316 is a narrow-band oxygen sensor with 4 wires, sold as a direct-fit part.
How can I tell an oxygen sensor like this is going bad?
The engine may run poorly, fuel use may rise or the malfunction indicator light may come on. Newer vehicles may also store a fault code related to the sensor.
What does the coating on this oxygen sensor do?
The coating on the electrode surfaces protects them from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes use a gas-permeable platinum layer.
