What Causes Abnormal Noise When Pressing the Accelerator Pedal?

[FinnDella]

There are three main reasons for abnormal noise when pressing the accelerator pedal. Fuel Pump Motor Noise: When the internal components of the fuel pump motor are worn or contaminated with impurities, abnormal noise occurs when pressing the accelerator. This issue requires replacing the fuel pump. Throttle Body Noise: Modern throttle bodies use electronic control, with a motor regulating the valve opening and closing. When the motor gears wear out, insufficient engagement causes noise. Excessive carbon deposits or sludge in the throttle body can also lead to noise. Cleaning the throttle body may resolve this. Clutch Release Bearing Damage: Incomplete clutch disengagement generates noise, requiring removal of the clutch to replace the release bearing.
