Walker Products 350-34089 oxygen sensor for the 2001-2010 Ford Escape V6 3.0L, the 2009-2010 Escape 4-cylinder 2.5L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel.
- Four-wire narrow-band design
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34089 oxygen sensor
- Fits: 2001-2010 Ford Escape V6 3.0L, the 2009-2010 Escape 4-cylinder 2.5L and other vehicles
- Position: upstream, downstream, upstream left, upstream right, downstream left, downstream right, downstream front or downstream rear
- Condition: New
A failing sensor might cause rough running, higher fuel consumption, higher emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is the problem; a vacuum leak can also make an engine run poorly. Also check the wiring harness and connector for physical damage.
Fits
The 2007-2009 Ford Fusion V6 3.0L and the 2010 Fusion 4-cylinder 2.5L or V6 3.5L take this sensor, as do the 1998-2000 Ford Ranger V6 3.0L, the 1998-2001 Ranger 4-cylinder 2.5L, the 1998-2003 Ranger V6 4.0L, the 2004-2006 Ranger V6 3.0L, the 2006 Ranger V6 4.0L and the 2006-2010 Ranger 4-cylinder 2.3L, and many other vehicles. A 2008 Ford Escape V6 3.0L oxygen sensor is this part number. So is the O2 sensor for a 2002 Ford Escape V6 3.0L. This listing is one sensor; the fitment lists one per application.

Frequently Asked Questions
Is this the right O2 sensor for a 2001-2010 Ford Escape V6 3.0L?
Yes. Walker Products 350-34089 fits the 2001-2010 Ford Escape V6 3.0L and the 2009-2010 Escape 4-cylinder 2.5L. For any other car, look up your own vehicle in the "Vehicles it fits" section.
Is this the Ford Ranger oxygen sensor for the 2006-2010 Ranger 4-cylinder 2.3L?
Yes. Walker Products 350-34089 is listed for the 2006-2010 Ford Ranger 4-cylinder 2.3L, with one sensor per application.
What type of sensor is this, and how many wires does it have?
This oxygen sensor is a narrow-band, direct-fit unit with four wires and an M18 - 1.5 thread.
What can a worn narrow-band oxygen sensor do to my engine?
It can lead to rough running, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light. Newer vehicles store fault codes in the ECU, and a shop can read them.
What are the electrodes on this Walker oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases.
