I tried going to Autozone to see if they would read the codes, but they told me they no longer do that as of mid 2008. I went to AAMCO, I had to leave my car there for a whole day just to see what the codes were. Being its my only car I didn't have time for that. The car is very sluggish as you press the accelerator and jerks a little as you increase in speed. I have a couple of questions.1- where is the connector to extract the codes? 2- what pins do I jumper? I read somewhere that its pin 8 and pin 13. I am familiar with working on cars (mostly GM's), just not on hondas, please help. P.S. Is there a sequence or pattern that I should know about when it flashes the codes to me?

This is how you check your own cel (Check Engine Light), at home, without driving to a mechanic, auto store, dealer. Numbers for the light are listed farther below.

5 Easy to Follow Steps:
1) Get a CEL

2) On the passener side, remove the kick panel at the floor.
Behind it, is your ecu and a jumper plug.

3) Locate the jumper plug (Civic 92-95 is grey, 96-00 its blue). Its a 2 pin plug.
(I am not sure if the connector is in the same location for all hondas..I assume so - I dont know all the connector colors...)

For EK, there is 1 brown wire and 1 black wire

For EG, there is 1 tan wire and 1 green

4) WITH THE CAR OFF, insert either a 2pin connector clip, or loop a thin enough piece of wire into both holes on the connector.

5) Back in the driver's seat, turn the key to the 'ON' position. The CEL light will come on at startup, like normal, but it will then begin to flash.
**By counting the number of flashes, you can decipher the CEL #.
SHORT flashes are single digits (1/2 second)
LONG flashes are 10's (1 second)
