    How the manifold air-pressure and temperature sensor for two-wheelers works


    The manifold air-pressure sensor with temperature sensor measures the pressure and air temperature in the intake manifold. The volume of air that reaches the engine cylinder can be calculated from the measured air pressure and the engine speed. This input variable is used to calculate the amount of fuel that needs to be injected.

    The micromechanical sensor contains a piezoresistive sensor element, which generates a measurable electrical voltage when pressure is applied. This voltage is then used in measuring the air pressure. The temperature sensor measures the intake air temperature, allowing the engine management system to adjust the amount of injected fuel.

    Technical characteristics:

    • Sensor measures the pressure of the intake air and the boost pressure
    • Pressure ranges of 115, 250, 300 and 400 kPa (absolute pressure)
    • Silicon micromechanics, 1-chip concept
    • Integrated temperature sensor optional
    • Operating temperature: -40 °C to +140 °C
    • Analog output
  • Customer benefits
