A failing oxygen sensor can show up as a check engine light, a rough idle or poorer fuel economy. These signs alone do not prove the sensor is the problem, since an exhaust leak can also throw off the readings.

Fits

It fits a wide range of makes and models. Besides the Altima above, it works as an oxygen sensor for the 1998-2004 Nissan Frontier 4-cylinder 2.4L and the 1999-2004 Frontier V6 3.3L. This listing is one sensor. The vehicles named here take one each, and some other vehicles take two, one at each position.
