What is the reason why the throttle won't open?

Come on, the throttle won't open. There may be a problem with the throttle control. First check whether the signals of the accelerator pedal position sensor and the accelerator position sensor are good, whether the resistance of the accelerator motor is normal, and whether the circuit from the computer to the sensor is good. If there is a problem, solve it. Throttle is a controllable valve to regulate the air entering the engine. It has two types: traditional cable throttle valve and electronic throttle valve. After the gas enters the intake pipe, it is mixed with gasoline to form a combustible mixture, which will burn during operation. It is connected with the air filter and the engine block. The traditional engine throttle control mechanism works through cables or pull rods. One end of the cable or pull rod is connected with the accelerator pedal, and the other end is connected with the accelerator connecting rod plate. The key of electronic throttle is to adjust the throttle opening according to the energy required by the engine through the throttle position sensor, and then adjust the intake air.
