Optimized Fuel Ratio Sensor - Denso 234-9008 Review

Arrived quickly and fitted perfectly. The machine works great with the part installed. The only potential problem I have is described by another reviewer. The part came in a DENSO box with DENSO Anti-Seize, but the part number and markings have been removed making it difficult to tell if it really is DENSO 234-9008. This part has been installed in my car for about 3 weeks and so far I haven't had any problems.

Worked great in my Highlander Sport V6 2008 AWD. I didn't even have to reset the codes. The check engine light went out immediately after installation. The package comes with an attached plug and a small packet of anti-seize paste. Went no problem for a fraction of the cost to buy locally. I've been using Denso sensors for years and none of them have died. None, and I typically keep my cars for 15 years.

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…
