What is the working principle of the throttle position sensor of 20 13 Cruze car?

Some models not only convert the throttle position sensor into a voltage signal, but also convert the voltage signal into a percentage square wave signal with adjustable pulse width in the computer board through the V/F conversion circuit, which is mostly used for the automatic transmission control of Audi/Volkswagen cars.

The throttle position signal is mainly used to detect the air-fuel ratio in the intake air, and then control the fuel injection quantity of the nozzle. However, in computer board control, throttle position signal is often used as the required air intake mode, and air flow meter or pressure sensor signal is used as the actual air intake. Therefore, adjust the throttle position signal when detecting the computer board. Hope to adopt.
