Ever get a check engine light and wonder what the problem was? To find out just locate your ECU (for civics there under the dash on the passenger side under the carpet. To read the code turn the key to the second accessory position and count the number of blinking lights between pauses, then compare. Now these codes don't tell you the exact problem, but they will get you headed in the right direction.
