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

Hello, your situation is that there is something wrong with the throttle control. First, check whether the signals of the accelerator pedal position sensor and the accelerator position sensor are good, check whether the resistance of the accelerator motor is normal and whether the wiring between the computer version and the sensor is good. If there is a problem, fix it. I'm happy to answer your question. I hope I can help you. I wish you a happy car! If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
