Passat command throttle voltage 0.0 1 normal?

Not normal. When all the throttles of Passat are open, the voltage of the throttle position sensor is about 5v, and when the throttle is closed, the voltage between VCC and the throttle is normal, so the voltage of Passat throttle is 0.0 1. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful.
