Hey eveyone, I'm new to the whole Honda and Prelude scene. I bought a 1990 Prelude Si 4WS, 5SP with a B21A1. It has a check engine light on it and i got a list of trouble codes. I thought it was flashing a 5 which is mechanical problem with the MAP. I replaced the MAP, removed clock fuse for a few minutes, fired it up and the light came back on again. I'm guessing that wasn't it. I got back down and looked at my code again and now i'm second guessing myself. Here's my question: do you count the last "short" flash as part of the code number? It is flashing 4 slow flashes and then a 5th fast flash. Is this a code 4 or 5? if it is a 4 then apparently it is the Crank sensor, but I don't want to go replacing anymore parts until i know what code I'm actually reading. I'm not really used to this set up and any help would be greatly appreciated!!
