NTK 25592 sensor for the 2006-2013 Volvo C70 5-cylinder 2.5L and other vehicles reads exhaust oxygen and feeds closed-loop signals back to the ECU. This NTK sensor helps the ECU control the air-fuel ratio and lets the OBDII system flag problems with fuel delivery or catalytic converter efficiency.
A failing sensor can show up as a check engine light, poorer fuel economy or a rough idle. Those signs alone do not prove the sensor is the problem, since a vacuum leak can produce them too.
This sensor is a direct-fit replacement for the 2006-2013 Volvo C70 5-cylinder 2.5L, the 2007-2013 Volvo C30 5-cylinder 2.5L and the 2001-2003 Volvo S60 5-cylinder 2.4L, the 2001-2004 S60 5-cylinder 2.3L and the 2005-2009 S60 5-cylinder 2.4L or 2.5L. The listing is one sensor, and these Volvos take one apiece. If your Volvo, Saab or Saturn is not named here, look it up in the "Vehicles it fits" section.
