When the fuel filler door 2500 rotates, there is a sound of water flowing.

The sound of water flow at the throttle valve 2500 may be caused by the fault of the throttle position sensor or the fault of the accelerator pedal position sensor. It is recommended to go to the repair shop to check the specific reasons and repair them in time.

Throttle, also known as "throttle" and "throttle". Refers to the control device that controls the engine power. On the piston aero-engine, the throttle valve controls the opening of the carburetor to control the filling amount of the cylinder, thus determining the output power of the engine. On the gas turbine engine, the throttle valve controls the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine.
