I'm having the same problem. My CEL is on. It was cleared by a mechanic but has returned. I have a 1997 Acura 2.2 CL. I checked under and to the right of the glove box and found a blue connector for 2 wires. I undid it from the bracket and inserted the paper clip. This is a picture of the blue connector.

With the clip inserted, I turned the key to IGN but there aren't any flashes. It also seems that I couldn't short out the connector. Looking through the connector as well as I could, only blue plastic was apparent.
So,
[1] Do I have the correct connector?
[2] Have I shorted it out correctly?
[3] If so, what would no flashes mean?
Thanks for all the information on this site. First real trouble with the Acura in 120K miles except for a blocked A/C drip line that I fixed.
