What does the car EBC light mean?

EPC= electronic power control belongs to engine management system. During ignition, the engine control unit detects the electronic throttle system to detect the occurrence of a fault, and displays it through the yellow EPC light installed in the instrument cluster.

The electronic throttle uses a wire harness (wire) instead of a cable or a pull rod, a micro motor is installed on the throttle, and the throttle opening is driven by the motor. The so-called "wire transmission" means replacing the original mechanical transmission mechanism with wire.

principle of operation

The traditional cable throttle has one end connected to the accelerator pedal and the other end connected to the throttle through a steel wire, and its transmission ratio is 1: 1. That is to say, the throttle opening will be as much as you step on it, but in many cases, the throttle should not be opened at such a large angle, so the throttle opening at this time is not necessarily the most scientific. Although this method is direct, its control accuracy is poor. The electronic throttle controls the opening of the throttle through cables or wire harnesses to realize automatic control.
