Hi, I have a 1993 Honda civic, and my CEL just came on. I have looked everywhere for an obd1 devise and no One has it no and days. So I tried the paper clip do it yourself thing and it gave me 4 LONG blinks only. And it just keeps repeating it. I really don't understand how to pull the code of that. Someone told me that it was the crankshaft position sensor, and autozone told me that 93 civics don't have a crankshaft?? So I'm going crazy can anyone that has had the same problem tell me what for long blinks on a Honda 93 civic mean? Please have tried everything. It seems no one knows.
