Adjusting the TPS

The first that pops up is EGI, to check the engine parameters
then AT for information on the automatic transmission,
AC for checking out the air conditioning stuff,
and CC for the cruise control.

On the engine mode you can check the vehicle speed in both MPH or KPH.

But in the trans mode you can check either speed sensor #1, or #2,
in both MPH and KPH.

In EGI and AT you can check engine temp, in both farenheit and celsius,
and THOSE readings show the same...

More later.

(1) Exactly how did you produce/create two actual specific parameters, when you took the two different and separate TPS voltage readings quoted?

(2) Was a select monitor connected?

(3) Was the engine running?

(4) What in fact actually changed between taking the two readings of 0.48 and 0.5 volts?

As Joe has noted this is interesting information and is worth pursuing.
