Function of intake pressure sensor
It connects the intake manifold with a vacuum tube. With the different engine speed load, it senses the change of vacuum degree in the intake manifold, and then converts it from the change of internal resistance of the sensor to a voltage signal for the ECU computer to correct the fuel injection quantity and ignition timing angle.
That is to say, the ECU computer outputs 5V voltage to the intake pressure sensor, and then the voltage value is detected by the signal terminal. When the engine is idling, the voltage signal of the computer is about 1 ~ 1.5V, and it is about 4.5V when the throttle is fully open. ..
