What are the main components of the intake pressure sensor?
Hello, its function is mainly to detect the intake manifold vacuum pressure. In general, 4 lines, of which 3 lines are pressure sensors, and the other is the inlet temperature sensor line. Some also separate the pressure sensor from the intake temperature sensor. So there are only 3 lines. The 4 lines are respectively a power supply line 5V, a rail line, an air inlet pressure signal line and an air inlet temperature signal line.
The inlet pressure sensor is used to detect the resistance of Wheatstone bridge circuit, the resistance changes with the intake manifold pressure, the amplifier will detect the signal into the ECU, by ECU analysis of calculated pressure value
A varistor. A signal processing chip
