Code P06A8 Honda Description

The Main Central Processing Unit (CPU) and sub-CPU are built into the Powertrain Control Module (PCM). The main CPU supplies 3.3 V power voltage to the sub-CPU. The sub-CPU converts (A/D conversion) the supplied power voltage and outputs the A/D converted value to the main CPU via serial communication. The main CPU monitors the PCM internal 5 V power supply by comparing it with the received value (comparison power supply voltage (3.3 V)) from the sub-CPU. When the 5 V power supply is normal, the comparison power supply voltage (3.3 V) falls within a normal area. 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 Diagnostic Trouble Code (DTC). Voltage Common Collector (VCC)
