question....how do i read a code that comes on when driving the car.....


Way to check codes on your 92-95 civic.
If you go to passanger side kick panel and raise up the carpet u sould see your ecu. and above your ECU there will be a lil plug. iIts grey. with 2 wires coming out of it. One wire is black with a white stripe and the other is a red with a black strip.. I take a spare piece of thin speaker wire and cut off both ends so that the actual copper of the wire is showion on both ends. i twist up both ends so that they are in a nice point. stick one end of the wire into the fist socket on the plug. The other end of the wire into the other socket. Turn your key to the ON position.. dont start your car. just to the ON position. Watch your check engine light on your cluster. it will flash.. 1 long flash is 10. the quick flashes are one. so if ur CEL goes !.....!!! that is a code 13. !....!....!!!!! code 25. then take the code #'s and hop on this thread and see what it is. i hope i could help you all.

Here is a how to video for checking CEL Right Click Save As (http://www.we-todd-did-racing.com/wetoddimage.wtdr?i=wMzc4NjA5NnM0MTNkZmQzMXk1NDE%3D )

here is a pic of the Jumper to check the codes
