What is the cause of abnormal throttle sound?

Abnormal sound of throttle valve is caused by excessive carbon deposition on throttle valve. The specific reasons and solutions are as follows: Causes of abnormal throttle sound: The existing throttles are all electronic throttles, so it is the motor that controls the opening and closing of the valve. When the motor gear is worn, it is not fully meshed, resulting in abnormal sound. When the throttle deposits too much sludge, it will also cause abnormal noise of the throttle. The throttle can be cleaned. If the motor is damaged, it is necessary to remove the throttle and replace the servo motor. If the throttle is abnormal, first check whether the instrument or workbench is loose, and then check the transmission. If there is oil stain inside, the transmission oil pump will make abnormal noise. Solution to abnormal sound of throttle valve: When cleaning the throttle valve, it is not necessary to disassemble it, but the steam inlet seal part must be cleaned, and the idling motor must be removed before cleaning. Borrowing and cleaning syringes has advantages and disadvantages. It is generally recommended that the maintenance station should not disassemble and clean to prevent other unnecessary waste, such as replacing the sealing ring or installing some other gaskets after disassembly, or leaking oil and gas during disassembly and assembly, which will delay the owner's time.
