Walker Products 350-34254 oxygen sensor for the 2011-2014 Ford F-150 V8 5.0L or 6.2L and other vehicles measures the oxygen in the exhaust gas. It is a 4-wire, direct-fit, narrow-band sensor for the downstream position.
- Coated electrode surfaces resist contamination and erosion from combustion residue and particulates in the exhaust gases
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Electrodes made of a gas-permeable platinum layer
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
Quick facts
- Part: Walker Products 350-34254 oxygen sensor
- Fits: 2011-2014 Ford F-150 V8 5.0L or 6.2L and other vehicles
- Position: Downstream, downstream left, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. Before you replace the sensor, rule out damage to its wiring harness and connector, which you can look over with the engine off, because other faults can light the same warning. If this sensor is the cause, this one replaces it.
Fits
Vehicles it fits include the 2011-2014 Ford F-150 V8 5.0L or 6.2L and the 2011-2014 Ford Lobo V8 5.0L. It is also an oxygen sensor for the 2016 Ford Figo and the 2017-2021 Figo 3-cylinder 1.5L or 4-cylinder 1.5L. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this a Ford F-150 oxygen sensor for the 2011-2014 F-150 with the V8 5.0L or 6.2L?
Yes. Walker Products 350-34254 fits the 2011-2014 Ford F-150 V8 5.0L or 6.2L, with a quantity of one.
How many oxygen sensors come in this Walker Products listing?
The listing holds one oxygen sensor, and the fitment calls for a quantity of one.
Is this a narrow-band or wideband oxygen sensor?
Narrow-band. Walker Products 350-34254 is a 4-wire, direct-fit narrow-band sensor.
What can a failing downstream oxygen sensor do to my engine?
It can show up as rough running, higher fuel consumption or a lit malfunction indicator light. A shop can read the stored fault codes to narrow it down.
What is the coating on the electrodes of this oxygen sensor for?
The coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces. The electrodes themselves are a gas-permeable platinum layer.
