Ling Du, there's no power to feed the throttle. What happened?

Ling Du, there's no power to feed the throttle. What happened? Ling Du, there's no power to feed the throttle. What happened? The throttle of Ling Du has no power supply for the following reasons: 1. Dirty throttle position sensor or unbalanced voltage will cause electronic throttle failure. 2. The choke is blocked, the oil pipe leaks, the power of the gasoline pump is reduced, and the gasoline filter is blocked. 3. Engine air intake, oil circuit and ignition system problems. The following information is relevant: 1. Judge whether there is a problem with the accelerator pedal of the car, because when stepping on the accelerator, the cable will drive the accelerator, that is, the accelerator, and there is a position sensor on the accelerator. 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 voltage. 2. 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. Failure or abnormality of any part of a system may lead to the situation that the accelerator of the car is trampled to death and the speed cannot be increased. @20 19
