DTC P0107: Barometric Pressure Circuit Low Input: Description
A 5-volt voltage is supplied to the BARO sensor power terminal (terminal No. 1) from the ECM (terminal No. 81 - M/T) or PCM (terminal No. 46 - A/T). The ground terminal (terminal No. 5) is grounded with ECM (terminal No. 40 - M/T) or PCM (terminal No. 16 - A/T). A voltage that is proportional to the atmospheric pressure is sent to the ECM (terminal No. 85 - M/T) or PCM (terminal No. 55 - A/T) from the BARO sensor output terminal (terminal No. 2). The BARO sensor outputs a voltage which corresponds to the barometric pressure. The ECM (M/T) or PCM (A/T) checks whether this voltage is within a specified range.
