Review on 🔧 234-4509 Denso O2 Oxygen Sensor - Enhance Engine Optimization with Advanced Technology by Steven Ali

Part fits my 2008 Toyota Highlander (2nd generation) perfectly. Fixed code P0037. Very quick to install if you follow other's suggestions. Sprayed the defective 02 sensor with a PB blaster a few hours before removing it. I tried removing it, but the sensor required a second shot of the PB Blaster. About 45 minutes after the second shot I was able to take off without any problems. I used a 22mm open end wrench. You could use a wrench or pliers. The wiring harness is 100% plug and play ready including mounting clips. If you have the hands you can do this and save some money. After the PB Blaster does the job, it takes 10 minutes. Cleared Codes with OBDII Key and App. Others have suggested that the code resets automatically, but that doesn't apply to my SUV.
