I got the same problem right now with my 92 Civic LX. I was driving and all of a sudden the speedometer decided to get a mind of its own and then died. Shortly after my CEL came on and i did the self test and got a 1 Long 7 Short. you'll prolly get the same code. It is as sleepersol stated your speed sensor has decided to give up on you. I opted not to get this problem taken care of since i was hoping to get a new tranny. I suggest u get that looked at A.S.A.P. It could be caught somewhere in ur tranny and could be tearing it apart slowly. If its still visible and everything if u got the money to fix it then go ahead if not. Dont. I didnt get mine fixed and i just put a piece of duct tape so i dont see the CEL ne more :chuckles:
