There's probably something in the FAQ, but with the engine not runninhg, have someone push on the accelerator pedal while you look under the hood. You'll see a cable pull on and rotate a pulley near the throttle body (where the air hose coming out of the air filter eventually feeds).

Now tell them to leave the accelerator pedal alone, and grab that pulley with your hand, and rotate it so it just leaves its endstop. You should hear a click as soon as it leaves the endstop, and again when you release it. If you do, then its likely OK, although knowing for sure that the computer is getting the switch signal is relatively more complicated. If you assume that the TPS function is OK, then cleaning the IAC is probably in order, especially if it's never been done before. Again, there should be something in the FAQ on this.
