how to check your CEL
#1
This is generally for all that own a 92-00 Civic. Sometime now and then we all will have a check engine light(CEL). The method for checking the 5th gen is the same as the 6th gen. Behind the passenger side kickpanel is your ECU. You may need to move the carpet a little to reach the small plug that sits in a rubber green casing. Pull out the smallest plug that looks like the pic below. One wire is black with a white stripe and the other is red with a black stripe. Now, you can either use a short piece of speaker wire(with the ends exposed) or my favorite, a paper clip to jump the two wires together.

Now, with either the speaker wire or paper clip in place, turn the key to the ON position, but be sure not to start up the car. Now, watch your CEL on the dash to see it flash. One long flash = 10. One short flash = 1. So, if you notice two long flashes and two short flashes, you've got a code 22. This is your vtec pressure valve.

Feel free to refer to this thread whenever you notice the granddaddy orange light on your cluster.
