Nissan Altima’s come equipped with anywhere from one to four oxygen sensors. The number of oxygen sensors your Nissan Altima has depends on the model and year. Most newer model Nissan Altimas have four oxygen sensors, two before the catalytic converter and two after.
Older model Nissan Altimas usually have only one or two oxygen sensors.
If you own a Nissan Altima, you might be wondering how many oxygen sensors it has. The answer is four. The Nissan Altima has two upstream and two downstream oxygen sensors.
The upstream oxygen sensors are located before the catalytic converter and help the engine control the air-fuel mixture. The downstream oxygen sensors are located after the catalytic converter and help monitor the exhaust gases.
Having four oxygen sensors helps ensure that your engine is running efficiently and that your emissions are low.
If one of your oxygen sensors isn’t working properly, it can cause your engine to run lean or rich, which can lead to increased emissions and decreased fuel economy.

How Much Does It Cost to Replace an O2 Sensor on a Nissan Altima?
An oxygen sensor is a key part of the emissions control system in your Nissan Altima. The job of the oxygen sensor is to monitor the exhaust gases coming out of the engine and report back to the computer. Based on this information, the computer can make adjustments to keep the engine running at peak efficiency.
Over time, oxygen sensors can become fouled by deposits and need to be replaced. Replacing an oxygen sensor on a Nissan Altima will typically cost between $200 and $400, depending on the year and model of your vehicle. Labor costs will be between $60 and $100, while parts will cost between $140 and $300.
Where is the Oxygen Sensor Located on a 2002 Nissan Altima?
The oxygen sensor is a key component in the emissions control system of your 2002 Nissan Altima. It is located in the exhaust pipe, before the catalytic converter. The oxygen sensor monitors the amount of oxygen in the exhaust and sends a signal to the engine computer.
The computer uses this information to adjust the air/fuel mixture so that it can be burned more efficiently.
