Your 2.5 Altima has 2 A/F ratio sensors. Sensor 1 (upstream) is at the top (pre-cat) and sensor 2 downstream (see diagram). You should replace both. Standing in front bumper and below the intake duct. You will see the heat shield. Remove the intake duct and heat shield. You will also need the O2 sensor socket. Use NGK/NTK sensors. BOSCH is also but a bit pricey.

Thanks for the information.

Is Sensor 2 is visible standing front of the vehicle or it is underneath the car?

Without removing anything I can see one sensor from the front not sure it is sensor 1 or 2..
