Intake manifold pressure sensor L4700-3823140 For YUCHAI 

Pressure sensor The function of the automobile intake pressure sensor is to connect the vacuum tube to the intake manifold. With the different speed loads of the engine, the vacuum change in the intake manifold is sensed, and then the change in the internal resistance of the sensor is converted into a voltage signal for ECU correction. Fuel injection quantity and ignition timing angle. And widely used in D-type injection system. The intake pressure sensor detects the absolute pressure of the intake manifold behind the throttle valve. It checks and measures the absolute pressure change 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 (EUC) , the EUC controls the basic fuel injection amount according to the magnitude of this signal voltage. Quality Guarantee :1 year, and strictly in accordance with the standard quality inspection
