18 electronic throttle spring failure of lefeng

The current maintenance method is to replace the throttle. In fact, the best way to repair the throttle spring is to replace the throttle motor. The throttle spring is broken, so a new motor can work normally.

The main reason of throttle failure is the damage of idle motor, the core component of throttle. The function of idle motor is to receive the output signal of ECU, and constantly change the idle position signal according to various idle working conditions, so that ECU can automatically correct idle fuel supply and ensure the engine idle stability. Once the idle motor signal is interrupted or the motor is damaged, the throttle of the throttle body enters the mechanical emergency state through the emergency spring.
