Hi all, when I first got this Honda, a few weeks ago, it had a check engine light. I checked it with a code reader and there was only one code (I forget the number). The code was for the IAC valve. I took that out and cleaned it and now I have a new code, P0141, for the O2 sensor heating circuit. My question is why did this code just throw after I fixed the IAC valve, and is there any chance the heating circuit isn't bad?

Thanks for any help!
