So I replaced them both again and the code comes up a soon as the car starts practically. I was told that the front and rear o2's are the same but if the rears aren't heated and I put them up front that would probably cause the codes right?
wow man ongoing issue. hope you get it fixed... my check engine light has been on for who knows how long now.. 6,7,8 months? I believe its due to the 02 sensors but I don't have any way of checking what the code is.
Did you ever get this issue fixed? I went back and forth with this the whole entire time I had the car. Nothing worked, I spend lots of $$$ trying to get those damn sensors not to throw a code. Hope you got it worked out.
Just something i noticed i didn't see anyone mention, and hope that they made sure the tune doesn't have adaptive learn disabled, as this will cause the primary o2's to throw codes. I forgot to enable this on mine after tuning and had same issue.
