Barometric Pressure Sensor: Description and Operation
PURPOSE
The atmospheric pressure sensor acts as an electronic barometer. This sensor's signal is used by the ECM to make air/fuel compensation based on
altitude requirements.
OPERATION
When the ignition is in the ON position, the sensor sends a signal to the ECM. A voltage signal is generated by the sensor based on atmospheric
pressure, and sent to the ECM.
