1. Basic information:
Intake manifold pressure sensor is a kind of semiconductor silicon piezoresistive effect way.
2. the core component introduction:
the sensor is mainly composed of the diffusion silicon core and the magnifying chip.
3. Introduce the working principle:
the intake manifold pressure sensor is installed on the intake manifold, which converts the intake pressure in the intake port into the voltage signal, and supplies the automobile ECU to collect. The ECU can read the signal to know the intake quantity in the engine cylinder, so as to control the amount of fuel injection and realize the best state of oil mixing.
4. Introduction of failure:
product use damage, there will be a fault alarm lamp on the automotive instrument, vehicle running fuel consumption, power and acceleration performance deterioration, with the computer board detection, there will be intake manifold pressure sensor fault code.
