It can be done with out removing the throttle body. I would rather see you remove the throttle body and clean it while you at it based on the year of your satty.
A high idle can be caused by several things.
A throttle plate that does not close all the way. Clean
A binding throttle cable. Lube
A gas pedal binding. Lube
Cruise contol linkage binding. Lube
A throttle position sensor linkage binding. Tap on it lightly and see if idle canges.
A vacuum leak. Repair
A stuck IAC valve. Clean
All of which can set this code.
The IAC valve has a little plunger on it that fits into a hole in the throttle body. That hole will normally also need cleaned. I would try cleaning the IAC and its port before purchasing a new one. I can send you instructions if you like. Pretty easy just an old toothbrush and some throttle body cleaner will do the trick.
Good luck and let us know. :)
