Azranger, I got your PM and replied. Basically, the code is set when a sender, for example, gets a bad read or sends info outside the acceptable threshhold. When that same sender has sent acceptable information four times in a row, the check engine light is cleared. I assume but do not know for positive that the code is probably cleared at the same time. There may be certain codes that are retained for one reason or another. I've read that to see the codes you first need to set the odometer to "trip" and other places say that's not necessary.
Skypilot, is that one of the techs out at Dick Edwards Ford? I bought my last three Ford trucks from Jim Jacobia at Dick Edwards. If you happen to see Jim, tell him 'hi' for me.
