y33 o2 sensor diagram?

[NateB29]

hi does anyone have an 02 sensor diagram for a y33? or are all sensors in the same location, as in sensor 2, bank 2 would be passenger side, after the cat? does that ring true for all nissans?

Should be correct. Make sure you check the FSM, which you can find at www.infinitiservicemanual.com

thanks. just for what its worth ive tried downloading the FSM a few times and many of the chapters take excruciatingly long to download and some wont even show up at all. not sure if anyone else has had this problem but ive encountered it every time i want to check something from the FSM

Sounds like a browser or connection issue - I've just tested on a few different machines and they pop up pretty quickly.

Keep in mind, they're huge documents, so reviewing them on-site might be wiser (and then just grabbing the pages you need).

the two aft o2 sensors are midway along the exhaust - I just changed my 2 out left and right - and it eliminated a knock P code plus the o2 codes - I started back on the exhaust and was working forward. Once I found them - you can see them once you jack up one side and they are both near the inside of the exhaust pipes - When I say inside - they point towards the drive shaft and are fairly easy to get to once you jack up the car on 4 stands - it took me longer to figure out where they initially were, jacking up the car and then finding them - once I found both sensors it took less than 5 minutes to change them out. How I finally completed everything was chocking the back wheels and jacking the front of the car up on two stands -

So ive checked the FSM but there is no diagram showing which side of the car each bank is and I want to make sure I am getting this right, it also doesnt help when there are some references to right and left bank, or bank 1 and bank 2. FSM calls it right bank and left bank, while the obdII reader calls it bank 1 and bank 2. SO... i have a code P0155, which is bank 2 sensor 1, while the FSM says that code is for the Right Bank. Upon the research ive done it looks to me like that is the passenger side, and the upstream sensor (the one before the cat). is this correct? thanks

for usdm, left right is referenced as you sit in the driver's seat.
