NTK 24320 air / fuel ratio sensor for the 2004-2006 Nissan Altima 4-cylinder 2.5L or V6 3.5L and other vehicles produces a linear output signal that tells the ECU how rich or lean the engine is running. As a wideband NTK air fuel ratio sensor, it lets the ECU make continuous, precise adjustments to the air-fuel mixture, where a conventional switching sensor only reports rich or lean.
A worn wideband sensor can show up as a check engine light, poor fuel economy or rough running, though those symptoms have other sources too. Before replacing it, look over the sensor's wiring and connector for damage with the engine off and cool. A shop can run live tests of the sensor signal.
The 2004-2006 Nissan Altima 4-cylinder 2.5L or V6 3.5L, the 2004-2008 Nissan Maxima V6 3.5L and the 2000-2006 Nissan Sentra 4-cylinder 1.8L and the 2004-2006 Sentra 4-cylinder 2.5L are among the vehicles this sensor fits, along with many more. The 2004-2008 Nissan Maxima V6 3.5L takes one of these sensors, and this listing is a single sensor. Look up your own car in the "Vehicles it fits" section to see if it is covered.
