Walker Products Oxygen Sensor P/N:250-54102
Walker Products 250-25041 oxygen sensor for the 2007 Audi S8 V10 5.2L reads the oxygen in the exhaust gas so the ECU can monitor combustion efficiency. This upstream sensor is a wide-band type.
A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light, though a damaged wiring harness or connector can be behind the same signs. Look both over for physical damage before you replace the sensor.
It is an oxygen sensor for the 2007 Audi S8 V10 5.2L, a direct-fit replacement for that car. This listing is one sensor, and the 2007 Audi S8 V10 5.2L takes one.
Fit and size
Build and materials
Is this the upstream oxygen sensor for the 2007 Audi S8 V10 5.2L?
Yes. Walker Products 250-25041 is an upstream oxygen sensor for the 2007 Audi S8 V10 5.2L, and that car takes one.
Is this Walker Products oxygen sensor a wide-band type?
Yes. Walker Products 250-25041 is a wide-band oxygen sensor, and its electrodes have a gas-permeable platinum layer.
What does the coating on this oxygen sensor do?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
How can I check whether the wiring on this oxygen sensor is damaged?
With the engine off and cool, look over the sensor, wiring harness and connector for physical damage. A shop can read any fault codes stored in the ECU.
What does the 250-25041 sensor report to the ECU?
It measures the oxygen in the exhaust gas and monitors the air-fuel ratio for combustion efficiency. It is made for its application and position to give the diagnostic feedback the ECU needs.
