What causes the electric current noise when stepping on the accelerator?

[JustinRose]

The causes of electric current noise when stepping on the accelerator are as follows: 1. Fuel pump motor noise: When there is internal wear or impurities in the fuel pump motor, it will produce abnormal noise when the accelerator is pressed. This issue requires replacing the fuel pump. 2. Throttle body noise: Modern throttle bodies use electronic throttle control, where the motor naturally controls the opening and closing of the valve. When the motor gears wear out, insufficient engagement causes abnormal noise. Excessive carbon deposits or sludge in the throttle body can also lead to noise. The throttle body can be cleaned, and if the motor is damaged, the throttle body needs to be disassembled to replace the appropriate motor.
