Absolute Pressure Sensor: Description and Operation

    The barometric pressure sensor senses changes in barometric pressure and provides this information, through an electrical signal, to the ECM. The
sensor produces a voltage signal of 3 - 4.5 volts to indicate barometric pressure. The voltage increases in proportion to increases in altitude (decreases in
barometric pressure). This sensor is normally used with the MAP sensor.
