Walker Products 250-241023 oxygen sensor for the 2012-2015 Ford Explorer 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas. Mounted downstream, this 4-wire narrow-band sensor gives the ECU the diagnostic feedback it expects for the specific application and fitment position.
- Measures oxygen levels in the exhaust gas to help fine-tune the air-fuel mixture and support fuel economy
- Reads exhaust oxygen content to track the air-fuel ratio and combustion efficiency
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-241023 oxygen sensor
- Fits: 2012-2015 Ford Explorer 4-cylinder 2.0L and other vehicles
- Position: Downstream
- Condition: New
A worn sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, because a damaged wiring harness or connector is another common cause, so look both over for physical damage as well.
Fits
The 2012-2015 Ford Explorer 4-cylinder 2.0L, the 2013-2016 Ford Escape 4-cylinder 2.0L, the 2013-2014 Ford Fusion 4-cylinder 1.6L and the 2013-2016 Fusion 4-cylinder 2.0L are among the many vehicles this sensor fits.

Frequently Asked Questions
Is this the right Ford Escape oxygen sensor for the 2013-2016 model with the 4-cylinder 2.0L?
Yes. Walker Products 250-241023 is listed for the 2013-2016 Ford Escape 4-cylinder 2.0L. Driving something else? Look up your own year and engine in the "Vehicles it fits" section.
Is this a 2013 Ford Explorer oxygen sensor replacement for the 2012-2015 model with the 4-cylinder 2.0L?
Yes. The 2012-2015 Ford Explorer 4-cylinder 2.0L is in the fitment, so the 2013 model year is covered by this downstream sensor.
Is this Walker Products oxygen sensor a narrow-band or wideband type?
It is narrow-band. Walker Products 250-241023 has four wires and a threaded M18 - 1.5 body.
What is the coating on this downstream oxygen sensor for?
The coating keeps combustion residue and particulates in the exhaust gas from contaminating or eroding the electrode surfaces, which are a gas-permeable platinum layer.
How do I tell if this downstream oxygen sensor is wearing out?
Rough running, higher fuel consumption or a lit malfunction indicator light can be signs. With the engine off and cool, look the sensor, wiring harness and connector over for physical damage.
