Squeaking Sound When Pressing the Accelerator Pedal
2 Answers
The causes of abnormal noise when pressing the accelerator pedal are as follows: 1. Abnormal noise from the fuel pump motor. When the fuel pump motor is internally worn or contaminated with impurities, it may produce abnormal noise when the accelerator is pressed. This issue requires replacing the fuel pump. 2. Abnormal noise from the throttle. Modern throttles are electronic, and the motor controls the opening and closing of the throttle valve. When the motor gears are worn, insufficient engagement can cause abnormal noise. Excessive carbon deposits or sludge in the throttle can also lead to noise. The throttle can be cleaned, but if the motor is damaged, the throttle must be disassembled to replace the servo motor.
My car makes a squeaking noise when I step on the gas pedal, and it's really annoying. I remember the same thing happened last summer. After parking on the side of the road, I checked near the gas pedal and found too much dust buildup and lack of lubrication at the pivot point. Spraying some specialized lubricant fixed it, but be careful not to get it on the brakes or carpet. For older cars, it could also be due to aging springs or loose pedal hinges—try shaking the pedal to see if it feels loose. Besides being noisy, ignoring it long-term might cause slower pedal response, affecting acceleration. Prevention is simple—just spray some lubricant when washing the car. If the noise persists after lubrication, it might be an issue with the engine bay belt, but checking the pedal first is the cheapest and safest option. In short, don’t delay—fixing it early saves hassle and money.
