Toyota Repair: Toyota Land Cruiser--1999 Throttle Control Motor Lock, toyota land cruiser, 10mm nuts

Question
How could I locate the throttle control motor in the land cruiser?

Answer
The throttle control motor is located on the throttle body, remove the two 10mm nuts and remove the metal shield covering the throttle body, is there a trouble code, can you let me know what the code number is because the throttle motors rarely are a problem, it may be something else.
