Question about 2003 Chevrolet Silverado 2500HD
Your problem can possibly be in the wiring in the circuits near the throttle body. The terminals can have weak crimps and broken wires at or within 4 inches of the connector to the throttle body and possibly the pcm. I have had to make wire harnesses for Aveo's with the same code problem.
Clear the code then gently wiggle the harness near the connectors to the pcm and the throttle body. Check the terminal tension to the wires at the throttle body in particular.

Tips for a great answer:
Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
Forced idle mode--The control module will perform the following actions:
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.
Ignore accelerator pedal input.
Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.
