Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

It sounds like these things are all related. When the a computer sees a problem in the Electronic throttle system, it will dissable traction control, and give the reduced engine power alert because the powertrain computer does not know the value of throttle postion.
Codes will need to be scanned in the computersto begin diagnosis.

IT MEANS THAT YOUR TRACTION CONTROL NEEDS SERVICING BY A DEALER, OR REPAIR CENTER. IT IS ALL COMPUTER CONTROLLED, LIKE A MAJORITY OF YOUR CARS COMPONENTS.
