I watched a video on YouTube and it looks like it's the o2 sensor the connects right under the driver's side from inside. I bought a Denso 234-4209 o2 sensor, but it says it's for downstream left. The guy who did the video posted a link for one that says downstream right. Which is weird since he clearly removed it from the left side.
Does it matter if it's downstream left or right? What is downstream, front? I'm guessing there are four o2 sensors then. I looked when I changed the transmission fluid, but I didn't have jack stands and only had 2x6 for extra height and couldn't see.
