O2 sensor location

[amosier23]

I'm getting a Bank 2 rich CEL and I think it may be the oxygen sensor. I know bank 2 is driver side, but how do I determine if it's sensor 1 or sensor 2. Also, where is the location of both. Pictures and you help is much appreciated. Thanks.

there should be other codes involved. what exactly is the code. you will need a live data stream to actually verify this. it can be several things. it can be easy as a software update to a leaking injector .

CEL Code

and the location is sensor 1 is up by the block second is half way down the system

The code I'm getting is P0175. I haven't noticed any change in MPGs or performance.

First of, bank to is the passenger side and a 175 does not mean you have a bad 02 sensor. You need to not do anything until you know more about your truck and what the codes mean otherwise you will just be throwing good money at it with no results.
