Chang 'an Xingka stepped on the gas pedal, but the gas pedal didn't respond.

1, there is something wrong with the throttle, for example, the throttle is blocked, the throttle position sensor is faulty, and the throttle position signal cannot be received.

2. The throttle valve is a device to adjust the intake air and fuel injection into the cylinder. I don't think it's the accelerator pedal, it's the accelerator opening.

3. The key function of throttle valve is to adjust the air intake, which will be related to the fuel injection.

4. If there is something wrong with the throttle, it will affect the small throttle opening and reduce the intake and fuel injection. If the fuel injection of a car is less, the power of the car will naturally weaken.

5. Others, such as air intake system, exhaust system, ignition system and fuel system, have problems in any part of these four systems, which may basically affect the truck's unresponsiveness when stepping on the accelerator.

6. There is something wrong with the fuel system, which may be that the fuel nozzle is blocked, which is related to the fuel supply demand specification. This situation requires cleaning the fuel injectors.
