I don't know the answer to your questions but have some information to relay.



I also get the 0500 code when checking. This is in addition to the P1693 code.



From research on this site it seems as if numerous people get this code and it isn't something to worry about. The common theory is that the speed signal doesn't get to the ECM or is corrupted for a very short time. This then triggers the code.



I'm not sure if anyone has changed the items you mentioned, but from the other posts I read it doesn't look as though the problem would be fixed.



If you are on to something that would be great though as I don't like having any codes. Especially on a brand new truck.

The P0500 is for no vehicle speed sensor signal detected during road load conditions. I get this code all the time in the winter when I use my high idle (from PS diesel) but any time you high idle your truck you will get this code. I also get the 1693 (Fault generated in the companion engine control module) with the 500 code. Unless you have no speedo when driving down the road I can see no problems. Basically the truck sees no speed and an high engine RPM and thinks something is wrong.



The sensor is on the rear diff on older trucks and comes from the rear anti lock breaking system on the newer trucks.



I clear the codes at the end of the winter with my OBD software and laptop.



I looked the code up here: www.autotap.com/codes.asp
