What does it mean when the EPC yellow light comes on after a car self-check?

It is normal for the EPC yellow light to come on after a car self-check. EPC is the indicator light for the Electronic Power Control system. When the car starts and enters the self-check mode, this light will illuminate and then turn off once the car starts normally. If the EPC light remains on after starting, there is no need to worry as long as the car can run. EPC stands for Electronic Power Control, also known as the electronic throttle, which consists of components like sensors and controllers. When a sensor malfunctions or detects an abnormal condition, the control system will take appropriate measures based on pre-set programs. The advantage of the EPC system is that the control unit can limit the throttle position according to various requirements.
