Ok so I did about 3 hours worth of searching and reading here on the org and im more confused that ever. im reading several different part number for this oxygen sensor which is the one located right after the bank 2(closest to radiator) cat in the "bend" of the cat. i tried calling autozone and then advance and got 2 different answers. Autozone said #13348 was the correct part and advance said #13350. up here I have seen #13374 and #13348...hence my confusion. Theses sensors are expensive so I wanna get the right one the first time. If someone knowledgeable in this category could shed some light on this I'd appreciate it. the diagram helps some which led me to think #13374 was the correct one. I have worked very hard to for the last 8 months to get rid of 6 yes i said it 6 codes and im down to this last one and hoping no others show up and no more check engine light for a little while anyways.

oh yea its a 2000 max with cali spec

 

WOW, man!! sounds like you've had it a little rough. I'll tell ya what... Toll Free: 888-800-9629...that's the number for bosch. Ask them your question, and repost...in the meantime, I'll crawl under my 2000 Cali Spec and take a look

 

did some more research beyond the org and found the part I needed and did my first oxygen sensor replacement...even though it took me three hours I learned a little more about my car and I didnt have to pay sum1 100 bucks to change it for me.
