The code indicates, "Throttle Control Airflow At Idle Too Low."
Okay, what I suggest is this. First, we need to confirm there are no intake manifold leaks or engine vacuum leaks. Here is a link that will explain how it's done:
If nothing is found, I suggest servicing the throttle body. If it is excessively dirty, that can cause this code as well. Here is a link that explains how it's done:
Also, make sure the air filter is clean, the air inlet tube between the throttle body and air filter box is clear, and do a general inspection for broken, cracked, or disconnected engine vacuum hoses. That part is explained in the first link I attached.
Let me know what you find or if you have other questions.
