Q: What does code P0E28 mean?

Drive Motor Inverter Temperature Sensor H Circuit. P0E28 indicates that the powertrain control module has detected an abnormal condition in the electrical circuit for the 'H' temperature sensor that monitors the drive motor inverter, which is the component that converts direct current to alternating current for the electric motor. The computer compares the sensor's signal to expected values and sets this code when the voltage or resistance falls outside the normal range, often due to a wiring fault or sensor failure.
