DTC Descriptors
DTC P0711
- Transmission Fluid Temperature Sensor Performance
DTC P0712
- Transmission Fluid Temperature Sensor Circuit Low Voltage
DTC P0713
- Transmission Fluid Temperature Sensor Circuit High Voltage
Circuit/System Description
The transmission fluid temperature sensor is located inside of the transmission Control Solenoid Valve Assembly which has no serviceable components. The transmission fluid temperature sensor provides transmission fluid temperature to the transmission control module (TCM). This fault is handled inside the TCM and no external circuits are involved.

* Engine speed is 400-7500 RPM for 5 seconds.
* Ignition voltage is 9-32 V.
* Throttle position signal is valid.
* Engine torque signal is valid.
P0712
* DTC P0712, P0716, P0717, P0722, or P0723 is not set.
* Engine speed is 400-7500 RPM for 5 seconds.
* Ignition voltage is 9-32 V.
P0713
* DTC P0713, P0716, P0717, P0722, or P0723 is not set.
* Engine speed is 400-7500 RPM for 5 seconds.
* Ignition voltage is 9-32 V.
Conditions for Setting the DTC
P0711
* TCM detects a 20-50°C (36-90°F) or greater difference between the transmission fluid temperature and the TCM substrate temperature, which depends on the average of the transmission fluid temperature, TCM substrate temperature, and TCM power up temperature.
* TCM detects a 20-50°C (36-90°F) or greater difference between the transmission fluid temperature and the TCM power up temperature, which depends on the average of the transmission fluid temperature, TCM substrate temperature, and TCM power up temperature.
* Above conditions have to be met for 5 minutes within a 6 minute period.
P0712
Transmission fluid temperature is 254°C (489°F) or greater for 1 minute.
P0713
Transmission fluid temperature is -254°C (-425°F) or less for 1 minute.
Action Taken When the DTC Sets
* DTCs P0711, P0712, and P0713 are Type B DTCs.
* TCM defaults to a calculated transmission fluid temperature based on the TCM temperature.
Conditions for Clearing the DTC
DTCs P0711, P0712, and P0713 are Type B DTCs.
Diagnostics Aids
The TCM temperature sensor is located inside of the Control Solenoid Valve Assembly and its output should resemble that of the transmission fluid temperature sensor's output.

Circuit/System Verification
1. Ignition ON, engine idling at the normal operating temperature.
2. Verify the scan tool Transmission Fluid Temperature parameter is between -254 and +254°C (-425 and +489°F).
• If not between -254 and +254°C (-425 and +489°F)
Replace the Q8 Control Solenoid Valve Assembly.
• If between -254 and +254°C (-425 and +489°F)
3. Verify the scan tool Transmission Fluid Temperature parameter increases greater than 2°C (3.5°F) after operating the vehicle at 64 km/h (40 mph) for 10 minutes.
• If the Temperature does not increase greater than 2°C (3.5°F)
Replace the Q8 Control Solenoid Valve Assembly.
• If the Temperature does increase greater than 2°C (3.5°F)
4. Verify the scan tool Transmission Fluid Temperature and the TCM Temperature parameters are within 20°C (68°F).
• If the Temperatures are not within 20°C (36°F)
Replace the Q8 Control Solenoid Valve Assembly.
• If the Temperatures are within 20°C (36°F)
5. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
6. Verify the DTC does not set.
• If a DTC sets
Replace the Q8 Control Solenoid Valve Assembly.
• If a DTC does not set
7. All OK
