Q: What does code P0A3C mean?

Drive Motor A Inverter Over Temperature. P0A3C means the temperature sensor inside the inverter that feeds drive motor A has reported a value above the safe limit, and the hybrid or electric control module has set the code to protect the power electronics. The computer is not guessing; it is reacting to a real over-temperature signal from the inverter's internal thermistor circuit.
