What are the reasons for a car's accelerator not responding?

[StAlina]

The reasons for a car's accelerator not responding are: the throttle sensor is too dirty or the voltage is imbalanced. The working principle of the accelerator is: when the accelerator pedal is pressed, it directly controls the throttle valve. The throttle valve opening will increase, allowing more air to enter the engine. At this time, the ECU will command the fuel injection system to inject more fuel, causing the engine speed to rise and the car to accelerate. Precautions for pressing the accelerator are: 1. Press and release the accelerator pedal gently, ensuring smooth and gradual movements; 2. Releasing the clutch should be closely coordinated with pressing the accelerator, with agile actions; 3. Choose an appropriate gear to ensure the engine operates mostly at medium speed and larger throttle openings to save fuel; 4. Before the car stops or the engine shuts down, the accelerator pedal should be released first, avoiding sudden revving of the engine without load.
