Walker Products 250-24954 oxygen sensor for the 2006-2007 Volkswagen Passat V6 3.6L and other vehicles reads the oxygen left in the exhaust gas. This direct-fit sensor gives the ECU the diagnostic feedback it expects.
- Four-wire, narrow-band construction made for its specific application and fitment position
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and exhaust particulates
- Tracks exhaust oxygen content and air-fuel ratio so the mixture can be fine-tuned for combustion efficiency and fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24954 oxygen sensor
- Fits: 2006-2007 Volkswagen Passat V6 3.6L and other vehicles
- Position: Downstream, downstream left, downstream front
- Condition: New
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light, though other faults can produce those symptoms too. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage first.
Fits
This oxygen sensor also fits 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. This listing is one sensor, and the 2006-2007 Volkswagen Passat V6 3.6L takes one.

Frequently Asked Questions
Is this oxygen sensor right for a 2006-2007 Volkswagen Passat V6 3.6L?
Yes, Walker Products 250-24954 fits the 2006-2007 Volkswagen Passat V6 3.6L, which takes one. If your car is not one of those named, look up its year and engine in the "Vehicles it fits" section.
Is this oxygen sensor for the 2013-2018 Audi S6 V8 4.0L?
Yes. This downstream sensor fits the 2013-2018 Audi S6 V8 4.0L, and the car takes one.
Is this Walker Products oxygen sensor upstream or downstream?
Downstream. Walker Products 250-24954 is listed for the downstream, downstream left and downstream front positions.
Is this oxygen sensor narrow-band or wideband?
Narrow-band. This oxygen sensor is a four-wire, direct-fit design made for its specific application and fitment position.
What does the coating on this sensor's electrodes do?
The electrodes use a gas-permeable platinum layer, and the coating shields their surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
