Are the downstream o2 sensors in a 1998 Nissan pathfinder the same for right and left sides?

SOURCE: location of a o2 sensor 2001 nissan maxima

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 .

The mass airflow can get dirty and you will get trouble codes for everything under the hood except for the mass airflow. Try unplugging your mass airflow and driving the vehicle, if your problem goes away you need to clean the sensor. Buy some mass airflow cleaner though because other cleaners can damage the coating on the sensor.

Are you looking for a serial number of a model number? The 1998 pathfinders have the VG33E engine (introduced in 1996)

It's located deep in the valley! Under the "LOWER intake manifold". copy and paste this link in your browser, or try clicking on it. It may be helpful to you.

I didn't find this link until after I had already disassembled my truck. This is the hardest job that I've taken on thus far, hope I can put it all back together properly. I changed the gaskets on the valve covers since I had everything off.
To answer your question: It's under your lower intake manifold, so it's a hard job!

SOURCE: what side is my o2 sensor (bank 1 sensor 1) on for

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.
