Background knowledge: In the electronic throttle (ETC) system, the electronic control module (ECU) instructs the throttle position motor to optimize the throttle opening according to the signal from the accelerator pedal position (APP) sensor, engine speed, vehicle speed, air conditioning energy consumption, etc. Limping home mode means that if the electronic control unit finds a fault in the electronic throttle system, it will command a close signal to the throttle position motor. At this time, a set of springs in the throttle will adjust the throttle to a fast idle state to ensure that the engine will not stall, but it will not be too fast.
