well if the light doesnt stay on, then there will be no codes to check, I have heard of lights coming on for no apparent reason then turning off, could be just a fluke thing.... if it does come on and stay on then you can pull the check engine code by jumping the connecter which is down near the passenger side door in that little compartment, unplug the connecter which has two ports and stick a paperclip in both ports then turn the car's ignition back on and the check light will blink however many times for which code the computer is showing, I dont know which codes are which for your car but you can find em on the net by doing an engine search under like "94 honda trouble codes" or something to that effect......
