Walker Products 350-34334 oxygen sensor for the 2012-2013 Volkswagen Jetta 4-cylinder 2.0L, the 2014-2018 Jetta 5-cylinder 2.5L, the 2015-2016 Jetta 4-cylinder 2.0L and other vehicles measures combustion efficiency from the amount of oxygen in the exhaust gas. This Walker Products oxygen sensor gives the ECU the diagnostic feedback it needs.
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned to support fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Made for a specific application and fitment position on the vehicle
Quick facts
- Part: Walker Products 350-34334 oxygen sensor
- Fits: the 2012-2013 Volkswagen Jetta 4-cylinder 2.0L, the 2014-2018 Jetta 5-cylinder 2.5L, the 2015-2016 Jetta 4-cylinder 2.0L and other vehicles
- Position: Center, downstream, downstream left, downstream right, downstream front, downstream rear
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can produce some of the same signs, so inspect both for physical damage and find the cause before you buy a sensor.
Fits
Beyond those Jetta years and engines, the list includes the 2012-2015 Volkswagen Passat 5-cylinder 2.5L and the 2012-2018 Passat V6 3.6L, where it works as a Passat oxygen sensor, and the 2012-2014 Volkswagen Golf 5-cylinder 2.5L. If your car is not named here, look it up in the "Vehicles it fits" section. This listing is one sensor, and the 2012-2013 Volkswagen Jetta 4-cylinder 2.0L takes one.

Frequently Asked Questions
Is this an oxygen sensor for a 2014-2018 VW Jetta 5-cylinder 2.5L?
Yes. Walker Products 350-34334 fits the 2014-2018 Volkswagen Jetta 5-cylinder 2.5L, as well as the 2012-2013 and 2015-2016 Jetta 4-cylinder 2.0L.
Is this the VW Golf oxygen sensor for a 2012-2014 Golf 5-cylinder 2.5L?
Yes. Walker Products 350-34334 fits the 2012-2014 Volkswagen Golf 5-cylinder 2.5L. Other Golf years and engines are in the "Vehicles it fits" section.
What thread size does this 4-wire narrow-band oxygen sensor have?
This oxygen sensor has an M18 - 1.5 thread and four wires. It is a narrow-band, direct-fit unit.
How can I tell if a narrow-band oxygen sensor is going bad?
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 fault codes to see which sensor is involved.
What does the platinum layer on this oxygen sensor do?
The electrodes of this Walker Products 350-34334 sensor are made of a gas-permeable platinum layer. A coating guards their surfaces against combustion residue and particulates in the exhaust.
