What does the Santa Fe fault code p2 1 19ets range performance mean?

Fault code P2 1 19 Chinese definition: throttle body range controlled by throttle actuator/performance category: fuel, air or emission control background knowledge: In the electronic throttle control (ETC) system, the function of the accelerator pedal position (APP) sensor is to transmit the position of the accelerator pedal to the throttle control module in the form of an electrical signal, which serves as a reference for the throttle actuator to control the throttle opening. The throttle actuator is a stepping motor, which is responsible for controlling the throttle opening according to the instruction of the throttle control module. The fault causes include the failure of the throttle return spring, the stuck throttle body and the failure of the electronic control module (PCM or ECM).
