DTC P0712
- Transmission Fluid Temperature (TFT) Sensor Circuit Low Voltage
DTC P0713
- Transmission Fluid Temperature (TFT) Sensor Circuit High Voltage
Circuit/System Description
The transmission fluid temperature (TFT) sensor is located inside of the transmission control module (TCM) assembly which has no serviceable
parts. The TFT sensor provides transmission fluid temperature to the TCM. This fault is handled inside the TCM and no external circuits are
involved.

DTC P0712
- Transmission Fluid Temperature (TFT) Sensor Circuit Low Voltage
DTC P0713
- Transmission Fluid Temperature (TFT) Sensor Circuit High Voltage
Diagnostic Fault Information
Typical Scan Tool Data
Circuit/System Description
The primary source of heat in the transmission is the drive motor generators. The drive motor generators are cooled by the transmission fluid. Hot
fluid exits the drive motor generators and flows to the transmission cooler supply line. The supply line connects to the cooler, which is in front of
the radiator. The transmission fluid cooler pipe assembly is equipped with an internal thermostat that opens at 80掳C (176掳F) for optimum
transmission operation and fuel economy. The transmission cooler pipe thermostat is part of the transmission fluid cooler pipe assembly, located
near the transmission and is not serviced separately. From the cooler, the fluid returns through the transmission fluid cooler pipe assembly and
enters the lubrication circuits. After lubricating the internal components, the fluid returns to the oil pan. The transmission fluid temperature sensor is
located in the control solenoid valve assembly and is not serviced separately.
Conditions for Running the DTC
* No OSS DTCs P0721, P0722, or P0723, P077B, P215C.
* The engine run time is greater than 5 seconds.
* The system voltage is 11-18 V.
* The estimated drive motor power loss is greater than 0.4 kw for 200 seconds.
* The OSS is greater than 200 RPM for 5 seconds.
P0711
* The Trans. Fluid Temp. parameter is -50 to +21掳C (-58 to +70掳F) at start up.
* The ECT is greater than 70掳C (158掳F).
* The ECT is greater than 55掳C (131掳F) at start up.
* The vehicle speed is greater than 8 km/h (5 mph) for 300 seconds.
* The vehicle speed is less than 200 km/h (124 mph) for 5 seconds.
* The TCM temperature parameter is -49 to +169掳C (-56 to +336掳F).
P0712
DTC P0712 is not failed this ignition cycle.
P0713
DTC P0713 is not failed this ignition cycle.
Conditions for Setting the DTC
P0711 - Fail Case 1
* Vehicle speed is greater than 8 km/h (5 mph) for 300 seconds cumulative.
* The Trans. Fluid Temp. parameter is between -50 and +21掳C (-58 and +70掳F).
* The Trans. Fluid Temp. parameter has changes by less than 2.0掳C (3.6掳F) in 100 seconds.
* The engine coolant temperature (ECT) is greater than 70掳C (158掳F).
* The ECT has increased by 55掳C (99掳F) since startup.
