Walker Products 350-35092 oxygen sensor for the 2014-2018 Volkswagen Jetta 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a 5-W wide-band type that supplies the diagnostic feedback the ECU needs.
- Measures oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Built for its specific application and fitment position
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-35092 oxygen sensor
- Fits: 2014-2018 Volkswagen Jetta 4-cylinder 1.8L and other vehicles
- Position: Upstream, upstream left, upstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light, and newer vehicles may store a fault code in the ECU. Before you replace this sensor, look over its wiring harness and connector for physical damage, and have a shop read any stored codes so you know the sensor is the cause.
Fits
It is listed for a wide range of Audi and Volkswagen models. Listed as a VW Jetta oxygen sensor for the 2014-2018 4-cylinder 1.8L, it takes one per car, as do the 2017-2018 Audi A4 4-cylinder 2.0L and the 2014-2017 Volkswagen Passat 4-cylinder 1.8L. This listing is one sensor. If your car is not named here, look it up in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the Audi A4 oxygen sensor for a 2017-2018 car with the 4-cylinder 2.0L?
Yes. Walker Products 350-35092 is listed for the 2017-2018 Audi A4 4-cylinder 2.0L, and that engine takes one sensor.
Is this Passat oxygen sensor right for a 2014-2017 Volkswagen with the 4-cylinder 1.8L?
Yes. It is listed for the 2014-2017 Volkswagen Passat 4-cylinder 1.8L, and one sensor is needed. Other Audi and Volkswagen models are in the "Vehicles it fits" section.
Is the Walker Products 350-35092 a wide-band or narrow-band oxygen sensor?
Walker Products 350-35092 is a 5-W wide-band oxygen sensor with an M18 - 1.5 thread.
Can a failing oxygen sensor increase exhaust emissions or turn on the malfunction indicator light?
It can. A failed sensor may make the engine run poorly, raise exhaust emissions or light the malfunction indicator; a shop can read the stored codes to see which system is involved.
What is the coating on this oxygen sensor's electrodes for?
The coating shields the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes themselves are a gas-permeable platinum layer.
