Review on 🚗 DOICOO 234-4530 Downstream Oxygen O2 Sensor | Compatible with Chevrolet Captiva Equinox GMC Terrain | Part #: 12639692 by Antonio Taveras

This O2 sensor was well packaged and housed in a plain white box. Installation on my Chevy Equinox was easy and the attached device fit just like the old one. After installing and clearing the code, it worked for about 2 days before the check engine light came on again. I checked the computer and it gave me various codes ranging from high voltage and low voltage to no activity at all. I cleaned the code again and it worked, then stopped again. I ended up having to send it back. It may have been the one I got, but I spent $10 on a better one that still works fine.
