The number of O2 sensors in a Nissan Sentra typically depends on the model year and engine type. Most modern Sentra models have two O2 sensors: one located before the catalytic converter (upstream) and one after it (downstream). However, some specific configurations or older models may have different arrangements. Always check the vehicle's manual or specifications for precise information.
o2 sensors are in the exhaust Usually in front of the catalytic converter near or in the exhaust manifold.
The are two o2 sensors in an 04 Sentra. One is called the front sensor, and it is in the engine compartment, in the exhaust manifold. The other, the rear one, is in the exhaust pipe under the car, past the catalytic converter.
Gas mileage also went down and I just replaced o2 sensors.
There is a total of 3 O2 sensors 2 Upstream and 1 Downstram

On a 2000 Nissan Sentra, the oxygen (O2) sensors are typically located in two places: one is positioned in the exhaust manifold before the catalytic converter (upstream O2 sensor), and the other is located after the catalytic converter (downstream O2 sensor). To access them, you may need to raise the vehicle and work underneath, as they are threaded into the exhaust system. Be sure to disconnect the electrical connectors before attempting to remove the sensors.
check your exhaust system there should be a wire running in to your exhaust tat is your o2 sensor good luck There are two o2 sensors, one in the engine and one coming out of the Cat Converter in the exhaust system.
there are 4 sensors 2 in the front and 2 in the back
The 1994 Nissan 300ZX is equipped with four oxygen (O2) sensors. It has two upstream sensors located before the catalytic converters and two downstream sensors located after them. This configuration helps monitor and optimize the engine's air-fuel mixture and emissions performance.
The 2005 Nissan Maxima is equipped with four oxygen (O2) sensors. There are two upstream (pre-catalytic converter) sensors and two downstream (post-catalytic converter) sensors. These sensors play a crucial role in monitoring the exhaust gases and helping to optimize engine performance and emissions.
Assuming you have the V-6 engine, it has two downstream (after the cats) O2 sensors and two upstream (before the cats) Air/Fuel Ratio Sensors. So the answer to your question is two O2 sensors.
