OEM Quality, easy to install.
This was a perfect replacement for a Toyota 4.0L v6 rear downstream o2 sensor. Item clip fit the factory harness securely, and had a protective plastic cap on the sensor to keep it clean during shipping. Replacement was easy to do, but hard to access laying on your back under a car. I did this on car ramps for the front. Stay safe and set the parking brake and use jack stands. This fixed/cleared my check engine light code (P040#)! Only minor thing ..and more of a suggestion is that the vendor provide a small tube of antis-seize lubricant to aid in installation.

The one I got was authentic. works and fit great.
234-4260 is a Direct fit for O2 sensor for 2009 Lexus ES350 sensor Bank 2 Sensor 2 aka Downstream Left. Whoever confused of which sensor it is this is it. I got it confirmed it's Denso authentic the one I have received. It looks more updated than the original denso from toyota denso that came out of the car. As of now it is going great and easy to install. Sensor looks high quality and it was on sale on amazon so the price is amazing.

Worked as needed to fix an engine code.
Worked perfectly for my 05 Tacoma, matching the plug is important when purchasing these.

Denso = Toyota
Denso is one of the OEM suppliers for Toyota (Spark plugs, Filters, sensors). The stuff you get at the dealers are Denso products with the Toyota label and marked up prices. This sensor worked as a direct replacement for my 2008 4 cyl Camry. However, the harness was shorter than the OEM one and there is quite a bit of tension from the harness to the exhaust.Also an FYI. AISIN is the other OEM supplier for Toyota (Cooling and mechanical)
