DTC P0A2A-11: Drive Motor "A" Temperature Sensor Circuit Short to Ground; DTC P0A2A-15: Drive Motor "A" Temperature Sensor Circuit Short to Auxiliary Battery or Open [12/2019 - 11/2023]: Description
WARNING: This page is about a different variant/trim than selected.
The resistance of the thermistor built into the motor temperature sensor changes in accordance with changes in the motor (MG2) temperature. The lower the motor (MG2) temperature, the higher the thermistor resistance. Conversely, the higher the motor (MG2) temperature, the lower the resistance.
HINT:
The term "drive motor A" indicates the motor (MG2).
