DESCRIPTION

Refer to the description for DTC P0712-856 Click here.

DTC No. INF Code DTC Detection Condition Trouble Area
P0711 883

As a result of comparing the fluid temperature and coolant temperature with the power switch on (READY), the fluid temperature exceeds a specified level while the coolant temperature is less than the specified level.

(2 trip detection)

  • Wire harness or connector

  • Hybrid vehicle transmission assembly

  • Power management control ECU

  • Transmission wire (transmission fluid temperature sensor)

Tech Tips

DTC P0711-833 will be set if the engine coolant temperature changes from 95°F (35°C) or less to 140°F (60°C) after the power switch is turned on (READY).
