I got a code (one flash) now if I am wrong go ahead and correct me but my code is o2 sensor. I just put a b16 in my 95 civic cx and I can not get rid of this code. I have it wired up and I have tried wiring it up a few different ways and it is killing me. The o2 sensor its self is brand new. The weird thing is that when I clear the code by pulling the fuse or neg. bat. cable and then check for the code immediatly the code is still there even before starting the car for the first time. I dont know where my problem lies but lots of input might help. Thanks guys and sorry for being long. HELP

 

are you sure you are checking the code correctly?? how did you check it??
