3.5.7.10 P0711

DTC P0711 Oil temperature of transmission is too high

The transmission control unit (TCU) monitors the temperature of the transmission oil. If the vehicle cools, the
system is unable to maintain a normal automatic transmission oil temperature, and the sensor control unit will
adopt preventive measure to prevent from damaging the parts of the vehicle, such as transmission and the like.

The transmitter control unit also monitors for the temperature variation rate according to the current operation
status (performance). If the temperature sensor performance is out of the predetermined normal value, set DTC as
P0711.

4. Diagnostic

procedures:

Note: Before carrying out this diagnosis step, observe the data list on fault diagnosis tester and analyze the
accuracy of the data, as these will help with quick diagnosis.

1

Read the fault code again after clearing away the fault code to check if fault codes, except DTC
P0711 exist in the control system.

A. Connect fault diagnosis tester to the datalink connector.

B. Rotated ignition switch to ON position

C. Switch on fault diagnostic device power supply

D. Clear DTC code.

E. Reset reading fault code, and check if DTCs meet setting condition of fault code in current

Check if the automatic transmission oil level and oil quality accord with the standard.

See 3.5.7.2 Automatic transmission oil level check procedures.

3

Check if the engine coolant accords with the standard.

4

Check if the automatic transmission cooling system leaks and is blocked or the pipeline is damaged.

5

Check if the engine cooling system leaks and is blocked or the pipeline is damaged.

Refer to2.8.7 diagnostic information and procedures.
