Q: What does code P2C8E mean?

DC/DC Converter Temperature Sensor D Circuit Low. P2C8E indicates that the powertrain control module has detected a low voltage condition on the signal circuit of the temperature sensor that monitors the DC/DC converter, which is the component that steps high-voltage battery power down to charge the 12-volt system. The computer expects a voltage within a specific range and sees a value below the lower limit, so it flags the sensor circuit as faulty.
