Generator Temperature Sensor Circuit Intermittent |
DTC SUMMARY
MALFUNCTION DESCRIPTION
These DTCs are stored when the generator temperature sensor output is abnormal. The cause of this malfunction may be one of the following:
Generator temperature sensor malfunction
- Internal generator temperature sensor malfunction
- Open or short in generator temperature sensor
Wire harness between the generator temperature sensor and inverter with converter assembly
- The connectors are not connected properly
- Foreign matter or water on the connector terminals
- Open or short in wire harness
HINT:
If any of these DTCs are stored, the generator temperature sensor is malfunctioning and the self-protection function may not operate. Therefore under certain high load driving condition, the temperature of the generator (MG1) becomes high. If the self-protection function does not operate, the generator (MG1) may malfunction and cause the vehicle to enter fail-safe mode.
DESCRIPTION
Refer to the description for DTC P0A3611.

DTC P0A361C
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off.
- Leave the vehicle as is for 5 hours or more and then check the values of the Data List items "Generator Temperature", "Motor Temperature" and "Inverter Coolant Water Temperature". [*1]
-
Turn the ignition switch to ON and turn the GTS on. [*2]
HINT:
[*1] to [*2]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform the normal judgment procedure again.
DTC P0A361F
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for 2 minutes or more.
- Turn the ignition switch to ON and turn the GTS on.
-
With ignition switch ON and wait for 5 seconds or more. [*1]
HINT:
[*1]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform the normal judgment procedure again.
