can you clarify which one you replaced?
there are throttle sensors (which are in the throttle body and are not adjustable)
and there are pedal position sensors (which are in the pedal control and are adjustable)

now as kevin stated those figures are for the pedal position sensors
i looked in the p7000 engine control manual and it shows this:
key on (engine stopped)pedal fully depressed:
sensor1: 4.2v (terminal 106)
sensor2: 2v (terminal 98)

key on (engine stopped) pedal fully released
sensor1: 0.6v (terminal 106)
sensor2: 0.3v (terminal 98)

not sure where he got his info from but appears to be reversed, maybe dyslexia..it happens ;o)

having a serial number of the truck might be helpful to some degree but as for this setting it probably isnt going to change much between the models and years.
