[200q20v] 1 MPH and O MPG on the Computer Display - What is the most likely cause?

[Steve Bednarski]

Here are the symptoms:

a.  1 MPH on the computer display (can be reset to zero)

b.  0 MPG on the same display

c.  Cruise control inoperative

d. Speedometer and odometer work

What is the most likely cause (and cure) for these problems?  I would guess
that they are all related.  Any help would be much appreciated.
