What does code P0EF3 mean?

Q: What does code P0EF3 mean?

Drive Motor C Temperature Sensor Circuit Range/Performance. P0EF3 indicates that the powertrain control module has detected an out-of-range or erratic signal from the temperature sensor monitoring the drive motor labeled C, which is typically the third traction motor in a multi-motor hybrid or electric vehicle. The computer compares the sensor voltage against expected values for the current operating conditions and flags a fault when the signal falls outside a calibrated window or behaves implausibly.
