Walker Products 250-24753 oxygen sensor for the 2009-2012 Audi Q5 V6 3.2L, the 2013-2017 Q5 V6 3.0L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is a direct-fit, 4-wire, narrow-band sensor made for its specific application and position.
- Monitors exhaust gases and reduces pollutants for a cleaner environment
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Measures oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Narrow-band sensor with four wires
Quick facts
- Part: Walker Products 250-24753 oxygen sensor
- Fits: 2009-2012 Audi Q5 V6 3.2L, the 2013-2017 Q5 V6 3.0L and other vehicles
- Position: Downstream left, downstream right
- Condition: New
A failing oxygen sensor can show up as an engine that runs poorly, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is at fault, since a damaged wiring harness or connector is another common source.
Fits
This sensor is listed for a wide range of Audi models. It is an Audi Q5 oxygen sensor for the 2009-2012 Q5 V6 3.2L and the 2013-2017 Q5 V6 3.0L, and the list also includes the 2010-2017 Audi S5 V6 3.0L and the 2014-2017 Audi SQ5 V6 3.0L. If your car is not one of these, open the "Vehicles it fits" section to check your exact model and engine. This listing is one downstream sensor, and the fitment calls for a quantity of one.

Frequently Asked Questions
Is this a good Audi Q5 oxygen sensor replacement for the 2013-2017 Q5 V6 3.0L?
Yes. Walker Products 250-24753 is listed for the 2013-2017 Audi Q5 V6 3.0L, and also for the 2009-2012 Q5 V6 3.2L. For other models, open the "Vehicles it fits" section.
Is this Walker Products oxygen sensor narrow-band or wide-band?
Walker Products 250-24753 is a narrow-band oxygen sensor with four wires. It is a direct-fit design made for its specific application and position.
Is this oxygen sensor upstream or downstream?
It is a downstream sensor, listed for the downstream left and downstream right positions. This listing is one sensor, and the fitment calls for a quantity of one.
Which signs can point to a failing oxygen sensor?
The engine can run poorly, fuel consumption or exhaust emissions can rise, or the malfunction indicator light can come on. Newer vehicles also store fault codes in the ECU, and some relate to the sensor.
What are the electrodes on this oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. The coating helps prevent contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
