15 Yuexiang v7 speed cannot adjust high energy.

15 yuexiang v7 speed high-energy adjustment. If the engine keeps high idle speed, this may be caused by a stuck throttle. Whether it is a mechanical throttle or an electronic throttle, the opening may be inaccurate due to carbon deposition. It is also possible that a sensor related to the engine working condition has an error signal, which makes the ECU increase the speed.

Causes of high speed

Excessive idle speed is mainly caused by excessive intake air or incorrect engine control signal at idle speed. Causes of excessive idle speed include air temperature sensor failure, water temperature sensor failure, throttle position sensor failure, air flow meter or intake manifold absolute pressure sensor failure, switch signal failure, idle speed control valve failure, throttle body failure, fuel injector failure, vacuum leakage, engine control unit failure or matching setting problem.
