Thank you for asking your question on JustAnswer.

 

The three codes you have listed are all electornic throttle body codes and in most cases if you are having problems it usually requires replacing the Throttle body assembly.

 

P2111 - Throttle Actuator Control (TAC) System - Stuck Open

HiCustomer

 

Thank you for asking your question on JustAnswer.

 

If you are still having problems with it , yes you can replace it your self. I would wait and see if the code returns and if so then go ahead and replace it. I have enclodes the instructions.Removal and Installation

CAUTION: The throttle body bore and plate area have a special coating and cannot be cleaned.

  1. Disconnect the battery ground cable.
  2. Remove the air cleaner and air cleaner intake pipe.
  3. Disconnect the electronic throttle control electrical connector.
  4. Disconnect the throttle position (TP) sensor electrical connector.
  5. Remove the 4 throttle body (TB) bolts and the TB and discard the TB O-ring seal.
    • To install, tighten to 9 Nm (80 lb-in ).
