This p-code is pointing to a fault internal of the Throttle Body. There a re a few things to check: Check for any vacuum leaks around throttle body, make sure the throttle body butterfly plate is clean and does not have build-up on it, and check to make sure your PCV is in working order. If these all check ok, suspect a faulty throttle actuator, which is built into the throttle body. The throttle body will need to be replaced as a unit.
