Walker Products Oxygen Sensor P/N:250-25144
Walker Products 250-25079 oxygen sensor for the 2006-2013 Volvo C70 5-cylinder 2.5L and other vehicles measures the oxygen level in the exhaust gas. This wide-band sensor is engineered as an original equipment replacement for its specific application and fitment position.
A rough-running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can mean the sensor is failing. A damaged wiring harness or connector can be behind them too, so track down the cause before you buy a new sensor.
This listing is one oxygen sensor for the 2008-2013 Volvo C30 5-cylinder 2.5L, and the 2006-2013 Volvo C70 5-cylinder 2.5L and the 2012 Volvo S60 5-cylinder 2.5L also take one. If your car is not one of these three, look it up in the "Vehicles it fits" section by year and engine.

Is this the oxygen sensor for a 2012 Volvo S60 5-cylinder 2.5L?
Yes. Walker Products 250-25079 is listed for the 2012 Volvo S60 5-cylinder 2.5L, and that car takes one sensor.
Is Walker Products 250-25079 a wide-band oxygen sensor?
Yes. Walker Products 250-25079 is a 5-W wide-band sensor that determines the oxygen content of the exhaust gas and monitors the air-fuel ratio.
What are the electrodes on this oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. A coating protects their surfaces from combustion residue and particulates in the exhaust.
How might a failing wide-band oxygen sensor show up?
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, which a shop can read.
Is the 250-25079 an upstream or downstream sensor?
Walker Products 250-25079 is an upstream sensor, listed as upstream, upstream left and upstream right. This listing is one sensor.
