Hi all! In need of a bit of help!

About a month or so ago my check engine light went on and it had 2 codes, one for the o2 sensor and one for the transmission. I knew there were a couple recalls so I had the transmission fixed by Chrysler. Fast forward to now. I need to do emissions and I obviously won't pass because of the check engine light and because of the o2 sensor. I had the car checked out yesterday and the transmission code was gone, so that was fixed, now it's just the o2 sensor. I've got the part coming in today.

Now I'm not very car savvy but I hope you might be able to help me? The tech said it's the bank 1, sensor 1, upstream cylinder side. I know I have 4 o2 sensors so I have absolutely no idea which one that is, haha! Could someone help so I don't end up changing the wrong one?

 

if u want pictures buy a service manual it will have them

 

That's the one that's hardest to get to. Bank 1 is the rear bank of cylinders. Sensor 1 is the upstream sensor, the one closest to the engine block.
Like Tech says, get a service manual. It'll pay for itself in no time if you're at all handy with tools.

 

where is the bank 2 sensor located, 0n the 2007 sebring
