Is the data of Shanghai Volkswagen LaVida intake pressure sensor 400 normal?

1, which is normal. The normal value of automobile intake pressure is between 27 and 27-30Kpa, when the vehicle is idling. 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.

2. There are many kinds of intake pressure sensors, such as piezoresistors and capacitors. Because of the advantages of fast response time, high detection accuracy, small size and flexible installation, varistor is widely used in D-type fuel injection system.
