Barometric 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.
