my orignal o2 sensor was going bad on my 96 civic ex. So i put a new one in (honda part). But now when i run a test, i get a engine code for a heated circuit malfunction for both sensors (bank 1 and 2). So i tested the o2 sensor itself, the resistance was right. I dont know where to check next with this problem. Any suggestions?

 

what engine code are you getting. did you test both O2's.
