    SYNOPSIS

    This article explains how to check your vehicles check engine light for MIL/CEL codes.
    MIL = Malfunction Indicator Light
    CEL = Check Engine Light

    MIL & CEL basically mean the same thing - your idiot light is on and you need to check it.


    88-91 CIVIC/CRX & 90-91 INTEGRA MIL/CEL CODE CHECKING :

    Info coming soon...
    92-00 CIVIC / 92-01 INTEGRA MIL/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 [Fig.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 [Fig.2]. Now, you can either make your own plug to "jump" the diagnostic connector[Fig.3-4] or you can use a paper clip to arc the diagnostic connector [Fig.5], so that your CEL light will begin to blink.

    I've always found that it's easiest 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 [Fig.6] and your CEL light should begin to blink [Fig.7].

    Once you get the CEL light to blink, here's the how the light is read:
    • 1 long blink(s) = an incriment of 10
    • short blink(s) = incriments of 1
    • short pause = continuation of same code
    • long pause = a break between codeis (if more than one CEL code being thrown)
    Video Example: Below is a video clip showing a sample of how to read a few CEL codes. The clip shows codes 22 (vtec solenoid), 41 (02 heater), and 19 (lock solenoid) being thrown, then repeats. You may want to watch the video a couple times to familiarize yourself with how the CEL light flashes numeric patterns, pauses, then flashes numeric patterns again.

    It may take you a few minutes to figure out what CEL code(s) and patterns are being thrown by your ecu.



    Special thanks to Jameson Malpezzi for this video clip.
