Walker Products 350-34543 oxygen sensor for the 2006-2007 Volkswagen Passat V6 3.6L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. This Walker Products oxygen sensor is a 4-wire, narrow-band, direct-fit unit for the downstream position.
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
- Electrodes carry a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
Quick facts
- Part: Walker Products 350-34543 oxygen sensor
- Fits: 2006-2007 Volkswagen Passat V6 3.6L and other vehicles
- Position: Downstream, downstream left, downstream front
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A vacuum leak, for example, can also make an engine run poorly, so those signs alone do not prove the sensor is the problem. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage.
Fits
This oxygen sensor is listed for a wide range of Audi and Volkswagen models, including the 2012-2014 Audi A8 Quattro W12 6.3L, the 2013-2018 A8 Quattro V8 4.0L and the 2013-2018 Audi S6 V8 4.0L.

Frequently Asked Questions
Is this oxygen sensor right for a 2006-2007 VW Passat V6 3.6L?
Yes. Walker Products 350-34543 is listed for the 2006-2007 Volkswagen Passat V6 3.6L, which takes one. If your car is not named on this page, look it up in the "Vehicles it fits" section.
Is this the S6 oxygen sensor for the 2013-2018 Audi S6 V8 4.0L?
Yes. Walker Products 350-34543 is listed for the 2013-2018 Audi S6 V8 4.0L, and that engine takes one sensor.
Is this a narrow-band or a wideband oxygen sensor?
This downstream sensor is narrow-band. It has four wires and an M18 - 1.5 thread.
How many sensors come with this 350-34543 listing?
This listing is one oxygen sensor, and the car takes one.
Which symptoms can mean a downstream oxygen sensor is failing?
Rough running, higher fuel use, more exhaust emissions or a malfunction indicator light can mean the sensor is failing. Newer vehicles also store fault codes in the ECU, and some relate to the sensor.
