The powertrain control module (PCM) monitors the internal 5 V power supply by comparing it to the A/D input power supply voltage (3.3 V). When the 5 V power supply is normal, the comparison power supply voltage (3.3 V) falls within a normal area. But if the 5 V power supply malfunctions, the comparison power supply voltage (3.3 V) exceeds the range of normal area. If the comparison power supply voltage is out of permissible range for a set time, the PCM detects a malfunction and stores a DTC.
