BARO
The scan tool displays
10-105 kPa (0-5 volts). The Barometric Pressure
(BARO) reading is determined from the Manifold Absolute Pressure
(MAP) sensor signal monitored during key up and Wide-Open Throttle
(WOT) conditions. The BARO is used in order to adjust the fuel delivery, and to spark advance in order to compensate for altitude changes.
