Here's an article on how to check the TPS:https://easyautodiagnostics.com/gm/4.3L-5.0L-5.7L/tp-sensor-tests-1
I checked mine on that other thread I posted, and even swapped it with another known good one (from another engine I have,) as well as the IAC. Both were fine and didn't see any change on mine.
In my experience, a malfunction of most sensors on these engines will throw a CEL. The ECU is programmed such that it will know if voltages are too low or too high or voltage is not even present, missing 5V reference, etc.
