P2CA6DC/DC Converter Temperature Sensor E Circuit Low

P2CA6 indicates that the powertrain control module has detected an abnormally low voltage signal on the temperature sensor circuit for DC/DC converter E, which is a voltage conversion device used in hybrid and electric vehicles. The computer compares the sensor's return voltage against expected values and flags the circuit as low when the signal falls below the calibrated threshold.
