• Oxygen readings help fine-tune the air-fuel mixture and support fuel economy
• Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio
• Monitors exhaust gases to help reduce pollutants

A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since an exhaust leak near it can skew the readings too. This listing is one sensor, and the listed engines take one.

The 2011 Ford Explorer V6 3.5L, the 2010-2012 Ford Escape V6 3.0L and 2010-2013 Escape 4-cylinder 2.5L, and the 2010 Ford Fusion V6 3.5L and 2010-2012 Fusion 4-cylinder 2.5L or V6 3.0L all fit this oxygen sensor, along with many other vehicles.
