When the speed of Shaanxi Automobile Delong car reaches 1500, it is impossible to refuel.

The oil supply computer should be debugged in the special maintenance center.

The EFI fuel supply technology adopted in Qidelong, Shaanxi Province, the computer will automatically control the fuel supply at idle speed to protect the engine from running at a certain speed. If the power supply is not triggered during heavy load, it is considered normal.

There are many factors that cause the speed of automobile fuel filler door not to go up. If there is a fault instrument, you can read the fault code of the car, and then know which module of the car reported the fault code, and then you can deal with the fault module.

Judgment of the reason why the accelerator can't accelerate after stepping on the bottom.

Try to judge that there is something wrong with the accelerator pedal, because when stepping on the accelerator, the cable will drive the accelerator, that is, the accelerator. 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 this signal.

Therefore, if the throttle position sensor is too dirty or the voltage is unbalanced, the electronic throttle will fail and the speed of the throttle will not go up.
