The truck didn't respond when it stepped on the gas pedal.

The truck didn't respond when it stepped on the accelerator, that is, the power of the car was insufficient. It is likely that there is something wrong with the throttle, such as the throttle is blocked, the throttle position sensor is faulty, and the throttle position signal cannot be received.

Throttle is a device that controls air intake and fuel injection into cylinders. The accelerator pedal we step on is actually not to control how much gasoline we spray, but to control the throttle opening.

The main function of the throttle valve is to control the air intake, which will affect the fuel injection.

If there is something wrong with the throttle, the throttle opening will be small, the air intake will be reduced, and the fuel injection will be reduced. If the fuel injection of the car is less, the power of the car will naturally weaken.

Others, such as air intake system, exhaust system, ignition system and fuel system, may cause the accelerator pedal of the truck to be stepped down unresponsively if any of these four components has problems.

There is something wrong with the fuel system, which may be that the fuel injector is blocked, which affects the starting fuel demand standard. This situation requires cleaning the fuel injectors.

Because you can't see the real car, you can't make an accurate judgment. The specific reasons still need professional inspection to determine, and only by determining where the problem lies can we prescribe the right medicine.
