Walker Products 350-34529 oxygen sensor for the 2012-2015 Ford Explorer 4-cylinder 2.0L and other vehicles reads the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency. Made for its specific application and fitment position, this downstream Walker Products oxygen sensor gives the ECU the diagnostic feedback it expects.
- Narrow-band sensor with 4 wires
- Electrodes coated with a gas-permeable platinum layer
- Platinum coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases
- Measures oxygen levels to help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34529 oxygen sensor
- Fits: 2012-2015 Ford Explorer 4-cylinder 2.0L and other vehicles
- Position: Downstream
- Condition: New
A rough-running engine, higher fuel use, more exhaust emissions or a lit malfunction indicator light can mean a failed sensor. A damaged wiring harness or connector can sit behind the same signs, so find the cause before buying. With the engine off, look over the sensor, harness and connector for physical damage.
Fits
Listed for many Ford and Lincoln models, this is an oxygen sensor replacement for 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. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this the Ford Escape oxygen sensor for the 2013-2016 Escape 4-cylinder 2.0L?
Yes. Walker Products 350-34529 is listed for the 2013-2016 Ford Escape 4-cylinder 2.0L, in the downstream position, one sensor per vehicle.
Will this oxygen sensor replacement fit a 2013 Ford Explorer 4-cylinder 2.0L?
Yes. The 2012-2015 Ford Explorer 4-cylinder 2.0L is listed, so the 2013 model is covered, and the sensor goes in the downstream position.
Is this a narrow-band or wideband oxygen sensor?
Walker Products 350-34529 is a narrow-band sensor with 4 wires, built as a direct-fit part for its specific application and position.
What signs can a failing downstream oxygen sensor show?
The engine can run poorly, fuel use or exhaust emissions can rise, or the malfunction indicator light can come on. A shop can read the stored ECU fault codes to narrow it down.
Does the platinum coating protect the electrodes on this sensor?
Yes. A gas-permeable platinum layer coats the electrodes, and the coating keeps combustion residue and particulates in the exhaust gases from contaminating or eroding the electrode surfaces.
