Intake Air Pressure Sensor(MAP). It uses a vacuum tube to connect the intake air. With different engine speed loads, it senses the vacuum change in the intake air, and then changes the internal resistance of the sensor into a voltage signal for the ECU to correct the fuel injection amount and ignition timing angle.
Principle: Intake air pressure sensor detects the absolute pressure of the intake air behind the throttle. It detects the change in the absolute pressure in the manifold according to the engine speed and load, and then converts it into a signal voltage and sends it to the engine control unit (ECU), The ECU controls the amount of basic fuel injection according to the magnitude of this signal voltage.
