Confusion over code 32
I have a 1990 F250, 7.5l (460). I pulled the codes today and the only Constant Memory code I have is 32. The book that came with the reader lists several problem descriptions for code 32, but only one that is said to be applicable for trucks; "(Trucks ONLY) EGR pressure feedback fault (1885-89 models)". My truck is a 90! 
So my question is - What is code 32 for a 1990 truck?
Any Ideas?

Going off of my memory, 32 is EGR position below minimum value. Test the voltage between the signal wire (don't remember the color, but orange should be 5V reference) and the signal return (black, brown, or gray with a red stripe) of the EGR position sensor. It should be around 0.3V, any less and that's probably the source of the code.
