Ok so I'm still having an issue with my 02 sensor. Still reading as being not active... I remember that the one I took replaced was on the car when I bought it and brought up the same code. What would cause an 02sensor that has worked for over 6 years and a new 02 sensor that only worked for 2 days read as inactive... I have electronics lol. I can delete the code drive it around casually and it will be fine, but as soon as I hit boost at WOT the MF'er lights up.
