- Measures oxygen levels to fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases and reduces pollutants
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and exhaust particulates
Quick facts
- Part: Walker Products 250-24127 oxygen sensor
- Fits: 2001-2010 Ford Escape V6 3.0L, the 2009-2010 Escape 4-cylinder 2.5L and other vehicles
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. An exhaust leak, a damaged wiring harness or connector, or a vacuum leak can be behind these signs too, so find the cause before you buy a sensor.
Fits
Walker Products lists this oxygen sensor for a wide range of Ford, Mazda and Mercury models, including the 2007-2009 Ford Fusion V6 3.0L and the 2010 Fusion 4-cylinder 2.5L or V6 3.5L.

Frequently Asked Questions
Is this the O2 sensor for a 2002 Ford Escape V6 3.0L?
Yes. Walker Products 250-24127 is listed for the 2001-2010 Ford Escape V6 3.0L and the 2009-2010 Escape 4-cylinder 2.5L.
Is 250-24127 the Ford Ranger oxygen sensor for a 2006-2010 Ford Ranger 4-cylinder 2.3L?
Yes. It is listed for the 2006-2010 Ford Ranger 4-cylinder 2.3L and for the 1998-2000 Ranger V6 3.0L. Use the "Vehicles it fits" section for other Ranger years and engines.
What sensor type and thread size does the Walker Products 250-24127 have?
The Walker Products 250-24127 is a narrow-band, 4-wire direct-fit sensor with an M18 - 1.5 thread.
How can I tell if this narrow-band oxygen sensor is failing?
A failing sensor can show up as poor engine running, higher fuel use or emissions, or a lit malfunction indicator light. With the engine off and cool, look the sensor, wiring harness and connector over for physical damage.
What does the coating on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
