Engine speed is greater than 500 rpm.
Immediately after the above condition occurs.

Action Taken When The DTC Sets

The Malfunction Indicator Lamp(MIL) will illuminate.
The TCM will record operating conditions at the time the diagnostic fails. This information will be stored in the Failure Records buffer.
Adopt Emergency/ Substitute mode and constant 4th gear by hydraulic control.
After ignition OFF/ON : 3rd gear by hydraulic control. Possible P, R and N also possible.
Power supply cut off to the EDS valve.

Conditions For Clearing The DTC

The MIL will turn OFF when the malfunction has not occurred after three-ignition cycle.
A history DTC will clear after 40 consecutive warm up cycles without a fault.
Using a scan tool can clear history DTCs.

Diagnostic Aids

Inspect the poor wiring harness connection for TCM connectors and transaxle wiring connectors.

Diagnostic Trouble Code(DTC) P0710

Transmission Fluid Temperature Sensor Circuit Malfunction

Circuit Description

The TFT sensor is a positive temperature coefficient thermistor (temperature sensitive resistor) that provides information to the TCM regarding transaxle fluid temperature. The temperature sensor is located in valve body. Calculated temperature is a factor used to determine the shift time and shift delay time.

The internal electrical resistance of the sensor varies in relation to the operating temperature of the transaxle fluid.

The TCM sends a 5 volt-reference signal to the temperature sensor and measures the voltage rise in the electrical circuit. A higher fluid temperature creates a higher resistance in the temperature sensor, thereby measuring a higher voltage signal.

The TCM measures this voltage as another input to help control line pressure, shift schedules and TCC apply. When transaxle fluid temperature reaches 120°C (248°F) the TCM enters "hot mode." Above this temperature the TCM modifies transaxle shift schedules and TCC apply in an attempt to reduce fluid temperature by reducing transaxle heat generation.

Conditions for Setting The DTC

The calculated temperature is compared with the predetermined min. and max. value.
If the temperature is less than min. value or greater than max value then the current temperature is regarded as of range and the corresponding error but will be set.

Action Taken When The DTC Sets

The hold lamp will blink.
The TCM will record operating conditions at the time the diagnostic fails. This information will be stored in the Failure Records buffer.
TCM assumes the transaxle fluid temperature is 60°C.
No influence on drivability.

Conditions for Clearing the MIL/DTC

The blinking hold lamp will turn OFF when the malfunction has not occurred after three-ignition cycle.
A history DTC will clear after 40 consecutive warm up cycles without a fault.
Using a scan tool can clear history DTCs.

Diagnostic Aids

When DTC P0710 sets, the possible cause of fault could be Transaxle Temperature Sensor.
