3.15 Barometer sensor troubleshooting (Pressure Sensor )
When the Barometer sensor does not work, the reason is chip problem. If the Barometer sensor IC is damaged, it will do
not work even thought power is supplied and MSM8974 controls normally. Also, Barometer is connected to Gyro/Accel
sensor directly. Therefore if the Barometer sensor does not work, change the Barometer sensor IC, Gyro/Accel sensor or
main board sequentially.
