DTC Descriptors

DTC P0711

- Transmission Fluid Temperature (TFT) Sensor Performance

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

components. The TFT sensor provides transmission fluid temperature to the TCM. This fault is handled inside the TCM and no external circuits are

involved.

Conditions for Running the DTC

* The engine speed is greater than 400 RPM for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

* Brake torque is not active.

* The engine torque signal is valid.

* The throttle position signal is valid.

P0712

* No DTCs P0712, P0716, P0717, P0722, or P0723.

* The engine speed is greater than 400 RPM for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

P0713

* No DTCs P0713, P0716, P0717, P0722, or P0723.

* The engine speed is greater than 400 RPM for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

Conditions for Setting the DTC

P0711

The difference between the transmission fluid temperature (TFT) and TCM temperature and the difference between the TFT and TCM power up

temperature are both greater than 20-50掳C (36-90掳F). The temperature threshold is dependent on the average temperature of the TFT, TCM

temperature, and TCM power up temperature.

P0712

The TFT is less than -74掳C (-101掳F) for 1 minute.
