Check Engini?

[AnimeKid]

I recently unpluged my mass airflow sensor on the exhaust manifold and forgot to plug it back in before starting the car and the check engine light came on and i get it to go off. It has been about a week since it came on. Is there any way to actually turn it off without spending bookoos of bucks at a shop.

That's the O2 sensor on the Exhaust. Pull the 7.5 amp fuse in the engine bay fuse box and let it reset the ECU. You have to have the O2 back in obviously. Though once everything is as it should be, the CEL should clear on it's own? It did with my IAT CEL anyway. Check the code to make sure it's actually what you think it is.

where do i check it on a 93 civic coupe with the d16z6

check the the right ofthe glove box (best to take the glovebox out), should see some wires and a couple of loose plugs (may be connected into a rubber block). the connection with 2 wires, you can "loop" the connection with a paperclip or piece of wire. Now, when you turn the key forward, the CEL will flash a code.
I suggest if you don't already have one, get a serv manual ASAP. Not only will it have the steps to check the codes, it will also show a chart with the code descriptions, and possible fixes

what happened AnimeKid?

 

[AnimeKid]

I havent had a chance to do it yet lol no money to get a manual.

Just to make sure the rubber plug you are talking about is green correct?

Yeah its green, should just be tucked up near the kick panel, jump it with a paper clip and turn the ignition to on and it should start flashing. Count long flashes as ten (so two long flashes is 20) and short flashes as one (three short flashes is 3.

Example, flaaaaaaaaaash flaaaaaaaaaash flash flash flash (23)
