About a month ago I replaced my catalytic converter, a few weeks later the O2 sensor went out. I replaced that too and I'm still getting a check engine light code for the same sensor. What else should I do? The guy at autozone said to make sure that the O2 sensor is getting power and that it's plugged in and it looks like it's getting power and it's plugged in.
Update- last two oil changes they've also said that my oil levels are dangerously low.. even though I've been changing the oil on time. Not sure if that's relevant or not.
