yes i am saying that there is no way a bad ecu will trigger a code 9. Obviously it's a possibility, since anything is possible, but not a very high one like you seem to think. I'm sure this guy would know if the motor is obd0 or not since i'm sure he would of stated if he changed over to obd-1 or not. It's in a crx, it's obd-0 unless he converted which is most likely not the case since he didn't say anything about it.your right i do know alot about hondas and cars in genral but who said it was a obdo motor,so are you saying there no way a bad ecu could do that, just because someone said it was a obdo dont mean it is i would double check to make sure
