reset CEL's: unplug ecu vs disconnect battery?

I know OBD2 civics have a 10A fuse in the underhood fuse box that you can pull out for 10-20 mins. Do our civics have a fuse like this in the fuse box?

Sorry for not answering the question, i guess i just doubled the question lol

- Wed Aug 06, 2008 4:23 pm #64921 cool. I've been unplugging the ECU because it is easiest to get to with a gutted interior, where the battery & fuse box have been hidden after a wiretuck. Now I gotta figure out why these codes aren't going away :x


thanks :thumb:
