Walker Products 350-34223 oxygen sensor for the 2005-2017 Volkswagen Jetta 5-cylinder 2.5L, the 2011-2015 Jetta 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. This Walker Products oxygen sensor keeps watch on the air-fuel ratio.
- Made for its specific application and position on the vehicle, and returns the diagnostic feedback the ECU needs
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gas
- Electrodes made of a gas-permeable platinum layer
- Narrow-band design with four wires
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34223 oxygen sensor
- Fits: the 2005-2017 Volkswagen Jetta 5-cylinder 2.5L, the 2011-2015 Jetta 4-cylinder 2.0L and other vehicles
- Position: Center, center right, upstream, downstream, downstream left, downstream right, downstream rear
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or light the malfunction indicator lamp. These signs alone do not prove the sensor is at fault, since an exhaust leak can produce some of them too. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage.
Fits
The 2005-2017 Volkswagen Jetta 5-cylinder 2.5L and the 2011-2015 Jetta 4-cylinder 2.0L take this sensor, as do the 2009 Audi A4 4-cylinder 1.8L, the 2009-2016 A4 4-cylinder 2.0L and many other vehicles. The same part is a Passat oxygen sensor for the 2012-2018 Volkswagen Passat 5-cylinder 2.5L.

Frequently Asked Questions
Does this Audi A4 oxygen sensor fit the 2009 Audi A4 4-cylinder 1.8L and the 2009-2016 A4 4-cylinder 2.0L?
Yes. Walker Products 350-34223 fits the 2009 Audi A4 4-cylinder 1.8L and the 2009-2016 A4 4-cylinder 2.0L, one sensor per application.
Does this VW Jetta oxygen sensor fit the 2005-2017 Volkswagen Jetta 5-cylinder 2.5L and the 2011-2015 Jetta 4-cylinder 2.0L?
Yes, Walker Products 350-34223 fits both. If your car is another model, enter its year and engine in the "Vehicles it fits" section to see whether this sensor applies.
Is this oxygen sensor narrow-band or wideband, and how many wires does it have?
This oxygen sensor is narrow-band, with four wires and an M18 - 1.5 thread.
What signs can a worn-out narrow-band oxygen sensor show?
The engine can run poorly, fuel consumption and exhaust emissions can rise, or the malfunction indicator lamp can come on. A shop can read the stored codes to see which sensor is involved.
What does the coating on this oxygen sensor's electrodes do?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes are a gas-permeable platinum layer.
