Welcome to FTE and the Big Bronco Forum. We will endeavor to get you the most accurate information we can muster.
The ITS is part and parcel to the IAC. Though I have never personally seen this code manifest itself on a Bronco, the issue stems from faulty IAC readings or movement. The suggestion would be to either clean or replace the IAC (Idle Air Control) solenoid/valve assembly. Cleaning is less expensive and often cures the problem. This combined with TP sensor fault codes would concern me as to whether the throttle plate stop screw has been messed with. Hopefully it has not and cleaning the IAC and replacing the TP sensor will rectify the problem.
