Review on Optimized Fuel Ratio Sensor - Denso 234-9008 by Dee Parson

I had code P0051 on my 2010 Toyota Highlander. The code says it's bank 2, sensor 1. The PN from my car was 89467-0E090. I couldn't find any info, more likely it was right or left BEFORE I ordered and removed the part, so I took a chance and ordered a left hand when I actually wanted a right hand. I researched further and it turned out that there is no difference other than the price difference, so I installed it and it works like a charm. The code will reset and that's it. I let it sit for 20 minutes and rode it over 15 miles. TARGET is gone. The two sensors are identical, so in case the other fails. I'll probably just order this again. It would only matter if the upstream and downstream sensors were swapped. You can rent oxygen sensor pullers at any auto parts store, and I'm in no way mechanically inclined. YouTube and the Haynes Directory only. Lol very happy with this purchase as it saved me a ton of money.
