Barometric Pressure Sensor: Description and Operation
BAROMETRIC PRESSURE SENSOR
Barometric Pressure (BARO) Sensor
The barometric pressure (BARO) sensor is a variable capacitor sensor that processes a signal indicating atmospheric pressure. This allows the PCM to
compensate for altitude. The PCM uses this information to calculate injection timing and glow plug control. The BARO sensor is located behind the
lower steering column opening finish panel.
A BARO sensor fault will result in an out-of-range signal to the PCM.
