p16a1 With e92 is it possible to bench test the throttle body/pedal

2016 caddy 6.2l l86, e92 pcm. Stock throttle body, different pedal, bench testing the pedal, I don't have the stock pedal to test. I had to hook up a tcm to stop from going into limp mode, and a resistor pot to the fuel hp pressure sensor. I'm still getting hp pressure codes, but reduced power went away. The pedal now moves the tb, but only to 35%?? I'm getting code p16a1 throttle position sensor high voltage.


Can you bench test the throttle to 100% on these e92s ? What's the minum required? Why does the fuel pressure need to be hooked up?
