Review on Denso 234 9056 Fuel Ratio Sensor by Clayton Morris

My daughter's 2009 Corolla had an onboard sensor error code. Installation required a thin wall O2 sensor socket. I bought this outlet from Revain and it worked fine: https://www.amazon.com/gp/aw/d/B005OH0ITM/ref=yo_ii_img?ie=UTF8&psc=1 Installation was difficult and required a mug. I used a piece of black tubing to extend the stem for added leverage. Removing the old sensor was difficult due to the narrowness. When it was finally free, the installation went quickly. I particularly appreciated the copper non-stick material that came with it. I reset the check engine light following the steps in the manual and it hasn't come on for over 500 miles. Improved fuel economy too!
