Walker Products 250-24955 oxygen sensor for the 2006-2010 Volkswagen Passat 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas. It monitors the air-fuel ratio to show how efficiently combustion is running.
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
- Monitors the exhaust gases to help reduce pollutants
- Measures oxygen levels to fine-tune the air-fuel mixture for fuel economy
- Electrodes made of a gas-permeable platinum layer
- 4-wire narrow-band design
- Built for a specific application and position on the vehicle, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-24955 oxygen sensor
- Fits: 2006-2010 Volkswagen Passat 4-cylinder 2.0L and other vehicles
- Position: upstream, downstream, downstream left, downstream right
- Condition: New
A failing sensor can show up as a rough-running engine, higher fuel consumption, more exhaust emissions or a check engine light, and newer vehicles may store a fault code. Those signs have other causes too, so with the engine off and cool, look over the sensor, wiring harness and connector for physical damage first. If the sensor is the cause, this one replaces it. The listing is one sensor, and each application takes one.
Fits
The 2006-2010 Volkswagen Passat 4-cylinder 2.0L, the 2009 Volkswagen Tiguan 4-cylinder 2.0L and the 2013-2018 Audi S6 V8 4.0L are among the vehicles it fits, and it is an S6 oxygen sensor for that V8 engine. Open the "Vehicles it fits" section to check your exact model and engine, since fit depends on both.

Frequently Asked Questions
Is this the right oxygen sensor for a 2006-2010 VW Passat 4-cylinder 2.0L?
Yes. Walker Products 250-24955 fits the 2006-2010 Volkswagen Passat 4-cylinder 2.0L, and the Passat takes one. For another car, open the "Vehicles it fits" section and check your model and engine.
Is this a VW Tiguan oxygen sensor for the 2009 Tiguan 4-cylinder 2.0L?
Yes. This oxygen sensor fits the 2009 Volkswagen Tiguan 4-cylinder 2.0L, and that engine takes one.
What thread does the Walker Products 250-24955 oxygen sensor have?
The Walker Products 250-24955 has an M18 - 1.5 thread. It is a narrow-band sensor with four wires.
Can a failing oxygen sensor turn on the check engine light?
Yes, a failed sensor can light the malfunction indicator light, and newer vehicles store fault codes in the ECU, some tied to the sensor. Other faults can set a light too, so a shop can read the codes.
Is this Walker Products oxygen sensor an upstream or downstream sensor?
Walker Products 250-24955 is listed for upstream, downstream, downstream left and downstream right positions. It is made for a specific application and fitment position, and this listing is one sensor.
