92-00 CIVIC / 92-01 INTEGRA CEL CODE CHECKING :
OBD1 & OBD2 Honda/Acura vehicles both use the same CEL checking procedure.

With a flashlight, you'll have to get yourself situated under the passenger side of your dash board and look to the right of the glove box.

You should see a green colored rubber block stuffed up under there [Pic.1].

Pull this block down. You should see two plugs residing inside of the block. Pull out the smaller of the two plugs (either a light grey or blue colored 2 wire plug) - this is the diagnostic plug [Pic.2].

Now, you can either make your own plug to "jump" the diagnostic connector[Pic.3-4] or you can use a paper clip to arc the diagnostic connector.

I've always found that it's easier to have the vehicle running while the CEL is ON before I "jump" the diagnostic plug. Once the diagnostic plug is "jumped", take a look at your gauge cluster and your CEL light should begin to blink

Once you get the CEL light to blink, here's the how the light is read:

*
1 long blink w/short pause = an incriment of 10
*
short blinks = incriments of 1
*
long pause = a break between codes

Example: say your CEL light is showing 1 long blink, short pause, 1 long blink quickly followed by 2 fast blinks, this is code 22 being flashed. Another example could be 10 fast blinks, semi-long pause, followed by 1 short blink - this would be two codes being flashed, code 10 & code 1.

It may take a few minutes to figure out what CEL codes are being thrown by your ecu.

After You Figure out the code being thrown by the ecu. You can refer to the honda service manual or haynes manual for your model car.
