Hi all:

I have a 96 pathfinder that needs o2 sensor replacement for bank 1 sensor 1 and bank 2 sensor 2. How can Iocate them? Your help to identify them and any tricks to replace them easily would be appreciated.

They're on the exhaust and unscrew from it. I dunno which side is which though.

Thanks guy! Anyone else can help, please?

bank 2 is the driver side. bank 1 is the passenger side.
Sensor 1 is before the cat, sensor 2 is after the cat.

What is the difference between before CAT and after CAT?

If you look at your exhaust system, right after you Y, there is a flater, but wider part to your pipe. This is your cat. one of the sensor is screwed into your exhaust before the cat, the second is screwed into your exhaust after the cat.
