The P0A38 fault code refers to the Generator Temperature Sensor Circuit being detected as low.

This fault code is related to the motor temperature sensor No. 2, which is responsible for detecting the temperature of the transaxle fluid in the vehicle. The resistance of the thermistor in the sensor changes with the variations in the transaxle fluid temperature.

The motor temperature sensor No.

2 is connected to the HV control ECU, which uses the signal from the sensor to limit the load on the motor and prevent overheating.

Additionally, the HV control ECU also checks for any wiring malfunction or sensor malfunction in the motor temperature sensor No.

2. If you encounter the P0A38 fault code, it indicates that there is an issue with the generator temperature sensor circuit being detected as low.

This could be due to a malfunction in the sensor itself or a wiring problem.

It is important to address this issue promptly to prevent any potential damage to the motor and ensure optimal performance of your vehicle.
