Output voltage at half-open throttle

2.5V The throttle valve is a controllable valve to control air to enter the engine. When the throttle valve is fully open, the voltage signal output by the potentiometer throttle position sensor should be about 0.5V, and the output signal voltage will increase with the increase of the throttle valve half-opening, and it should be about 5V when the throttle valve is fully open. When the throttle is half open, the output voltage is 2.5 volts. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful.
