P2112 Throttle Actuator Control System - Stuck Closed High
The P2112 code means the computer put the electronic throttle system into protection because the throttle plate stayed closed. It is a protective measure: the engine goes into limp mode and can stall or fail to accelerate. It almost always shows up with another code that points to the real cause, so read all the codes first.
