Under normal circumstances, there is no response after the accelerator pedal is pressed. What could be the reason?

If the accelerator pedal doesn't respond, it means that the power of the car is abnormal. Maybe the oil pump filter is dirty, or there is something wrong with the connection of the accelerator pedal, cable and accelerator. The fault of accelerator pedal reflects the abnormality of automobile power, which is realized through the coordination of intake system, ignition system and fuel system. If any component is abnormal, it may cause the engine power to drop, the accelerator pedal to be unresponsive, the car body to shake, the exhaust pipe to smoke and so on. When you step on the accelerator pedal, the cable will move the accelerator pedal. There is a position sensor on the throttle. The control unit knows the throttle opening according to the signal of the throttle position sensor, then calculates the corresponding signal voltage, and finally calculates the fuel injection quantity of the vehicle according to the single pressure of the signal.

Throttle is a control valve that controls the air entering the engine. Air enters the intake pipe and mixes with gasoline to form a combustible mixture, which is burned to do work. It connects the air filter with the engine cylinder and is called the throat of the automobile engine. Therefore, stepping on the accelerator pedal is not to control fuel injection, but to control air intake through the opening of the accelerator, and the automobile computer injects fuel into the air conditioner through air intake.

Therefore, when stepping on the accelerator pedal, the vehicle does not respond or shake. It is likely that the accelerator part of the vehicle has failed, such as the valve stuck and the accelerator position sensor failed at first. It is recommended to check the throttle. Throttle is a controllable valve that controls air to enter the engine. After entering the intake pipe, it is mixed with gasoline to form a combustible mixture, which is burned to do work. Therefore, the accelerator pedal is not used to control the fuel injection, but to control the air intake through the opening of the throttle, and the automobile computer controls the fuel injection through the air intake.
