I am trying to determine if my throttle valve is stuck. I have cleaned the throttle body thoroughly, however when putting things back together I decided to keep the main hose off so that I can look at it functioning. Starting it up the value does not move nor does it when revving the engine to the maximum the vehicle will allow. Should I see some movement in the throttle valve?

There might be enough airflow when close to closed that just increasing the fuel flow by the injector duty cycle is enough to get the engine to rev.

Does it fail to work when on the road and under load? It doesn't take much HP to just spin an engine faster if it's not loaded.

The PCM is constantly looking at the throttle valve position with TWO separate sensors, and if it's not at the angle it was commanded to go to, you'd get a SES light and it would throw a code. Don't look for problems that aren't there.
