Hello,I'm Danny.

That code is more directly related to the throttle actuator control system. Your pedal assembly acts as a potentiometer. If it's defective/malfunctioning it will trip the code P0228 and put the car into limp mode like you're experiencing. I've attached a picture below and circled in the red the sensor connection.Hope this helps and thanks for using 2CarPros.
