When the high beam is not turned on, the throttle failure is accompanied by flashing high beam and current buzz.

The automobile throttle controls the intake of the engine. The electronic control system (ECU) of the engine is also a computer. It senses the throttle opening according to the throttle position sensor installed on the throttle, and then controls the fuel injection quantity according to the signals of each sensor to realize the engine speed. It can also be said that the throttle is sealed with air. When it's not opened? There are two kinds of automobile throttle valves, 1, which are integrated with idle motor. This throttle valve is not completely closed when the engine rotates. The ECU will control the idle motor to automatically turn on to a certain angle, so that the idle speed of the engine can be kept at about 850 revolutions per minute. When accelerating, the throttle can be opened to the maximum according to your requirements, about 100 degrees. 2 Idle motor is installed separately. This kind of throttle closes at idle speed and opens at acceleration.
