Where is the OBD port in a 1993 Honda Civic?
I’m trying to help a friend out with troubleshooting what’s wrong with his ‘93 Civic. I told him to hook up a scan tool to scan for trouble codes, but he looked at me like I was speaking gibberish. Anyways, help me help him—where is the OBD port in a 1993 Honda Civic?

Your friend and his clueless look were actually onto something! There is no OBD-II port in a 1993
Honda Civic
. Instead, there should be a two-prong connector pin located behind the front passenger-side footwell panel**.OBD-II ports didn’t become the norm in vehicles until 1996, so a modern OBD-II scan tool won’t work here. Instead, you’ll have to grab a paper clip (perhaps your friend has one in his pocket or in a nearby desk drawer?), a pen, and some paper.
Open the front passenger door, and behind the footwell panel, you should see a blue or white connector pin. Untangle the paper clip and insert both ends into the pin’s two openings in order to short it. Now, turn the ignition to ON, and the Civic’s Check Engine Light will start to flash in a coded pattern (eg: one, one-two-three)—you can reference the owner’s manual to decipher the code and diagnose the problem affecting the Civic.
That said, if you’ve got no patience for analog troubleshooting methods (or your hapless friend), tell him to bring his Civic to a Honda dealership. Honda techs will be able to scan and diagnose any trouble codes and fix the problem.
