Isuzu's 4K600P car has a throttle of 3000 rpm and can't afford to refuel. What happened?

There are many factors that cause the speed of automobile fuel filler door not to go up. If we have a fault table, we can read the fault code of the car, then know which module of the car reported the fault code, and then we can deal with the fault module. But most car owners and friends don't have this kind of instrument, so we should step by step and determine what is going on according to the actual situation of the car.

First of all, we 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 the single pressure of 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.

If the fault of electronic throttle is eliminated, we should turn our attention to the intake system, oil circuit and ignition system of the engine. If any part of a system fails or is abnormal, it may lead to the situation that the accelerator of the car cannot step on the speed.
