P0A38
DTC P0A38-257 Generator Temperature Sensor Circuit LowDTC P0A39-259 Generator Temperature Sensor Circuit High
DESCRIPTION
DTC Detection Condition:
The No. 2 motor temperature sensor detects the temperature of the transaxle fluid. The resistance of the thermistor installed in the No. 2 motor temperature sensor varies with the changes in the transaxle fluid temperature. The construction in the No. 2 motor temperature sensor and how it is connected to the HV control ECU are the same as those of the No. 1 motor temperature sensor.
Based on the signal provided by the No. 2 motor temperature sensor, the HV control ECU limits the load to prevent the motor from overheating. Furthermore, the HV control ECU checks the No. 2 motor temperature sensor for a wiring malfunction and the sensor for a malfunction.
HINT: After confirming DTC P0A38 (INF 257) or P0A39 (INF 259), confirm MOTOR 2 TEMP in DIAGNOSIS / OBD/MOBD / HV ECU / DATA LIST using the intelligent tester.
