What is the voltage of the intake pressure sensor of Roewe 550?

It is normal that the voltage of the intake pressure sensor is 0-5v. It is normal that the voltage of the intake pressure sensor is 0-5v. The voltage of the intake pressure sensor increases with the increase of the throttle valve, to be precise, with the decrease of the vacuum degree of the intake manifold. The intake pressure sensor detects the absolute pressure of the intake manifold behind the throttle. It detects the change of absolute pressure in the manifold according to the engine speed and load, and then converts it into signal voltage and sends it to the ECU. The ECU controls the basic fuel injection quantity according to the signal voltage.
