If the measurement at the TPS terminals fall within the factory spec and you followed the procedure exactly then I would doubt the "universal" scanner reading.
Depending on the scanner, cheap to high end they are NOT all the same. AutoZone may be willing to use different model then you can compare the results.

You have the empirical data, as long as your methodology is not suspect.
