The P0A37 fault code refers to the Generator Temperature Sensor Circuit RangePerformance.

This code is triggered when the motor temperature sensor No. 2 detects an issue with the temperature of the transaxle fluid.

The resistance of the thermistor in the sensor changes with the fluid temperature. The HV control ECU uses the signal from this sensor to limit the load on the motor and prevent overheating.

The HV control ECU also checks for any wiring or sensor malfunctions related to the motor temperature sensor No. 2. If this fault code appears, it indicates a problem with the generator temperature sensor circuit and its performance.
