Question about 2000 Nissan Sentra
I got a p0141 code on my 2000 Nissan Sentra. I know it's O2 Sensor Bank 1 Sensor 2, but I'm not quite sure where it's at
Standing in front of the vehicle looking at the engine bank 1 sensor 2 is the sensor after the cat converter on the bank on your left
bank one is the left cat ---bank 2 is the right cat. Sensor 1 is the one before the cat and sensor 2 is the one after the cat on either side

Bank one is on the side of cylinder one. Cylinder one is typically on the driver side. Although, you have to be careful here. Just because the code mentioned the O2 sensor doesn't mean the sensor is bad. For instance, a code of P0171: sensor indicates lean, bank one sensor; one is not a bad sensor. That is a good sensor telling you that the engine is running lean on bank one. If you get a different code, then it could the be the sensor.

bank 1 refers to the side of the engine that #1 cylinder is on , and sensor 2 refers to downstream , after the catalytic converter. , this link shows bank 1 on a 2001 nissan maxima V6 being on the firewall side . if you had a 4 cylinder it would be downstream after the catalytic converter .

Bank 1 means it's on the same side as your cylinder 1
Sensor 1 is the sensor that is located before the catalytic converter.

do you mean P0171??
If so, then it means your MAF sensor may be dirty and needs to either be cleaned or replaced.
It could also mean there's a vacuum leak downstream of the MAF sensor
