o2 sensor code after replaceing
I have about 130k on my mini and have had the secondary o2 sensor code on for some time. I finally replaced the o2 sensor but the code came back. Has anyone experienced this? I thought maybe it may be the cat considering the mileage.
Was doing some research on this a bit ago. Sounded like some people were experiencing codes if they did not replace with OEM. See this thread.
