A check engine light, rough running or poor fuel economy can point to a worn oxygen sensor. These signs alone do not prove the sensor is the problem, since a vacuum leak can throw off fuel trim too. This listing is one sensor, and the 2005-2006 Nissan Altima V6 3.5L takes one.

Fits

The 2005-2006 Nissan Altima V6 3.5L, the 2005-2012 Nissan Frontier V6 4.0L and the 2005-2012 Nissan Pathfinder V6 4.0L take this sensor, and so do many other Nissan and Infiniti models. It works as a 2006 Nissan Altima O2 sensor and as an O2 sensor for the 2005 Nissan Altima, both with the V6 3.5L.
