Circuit/System Description
The transmission fluid temperature (TFT) sensor is located
inside of the transmission control solenoid valve assembly which
has no serviceable components. The TFT sensor provides transmission
fluid temperature to the transmission control module (TCM).
This fault is handled inside the TCM and no external circuits are
involved.

The engine speed is greater than 400 RPM for
5 seconds. |
• |
The ignition voltage is greater than
9.0 volts. |
• |
DTC P0712, P0716, P0717, P0722, or P0723 is not
set. |
P0713
• |
The engine speed is greater than 500 RPM for
5 seconds. |
• |
The ignition voltage is greater than
9.0 volts. |
• |
DTC P0713, P0716, P0717, P0722, or P0723 is

Conditions for Setting the DTC
P0711
The difference between the TFT and TCM temperature and the
difference between the TFT and TCM power up temperature are both
greater than 20-50°C (36-90°F) for 4 seconds. The
temperature threshold is dependent on the average temperature of
the TFT, TCM temperature, and TCM power up temperature.
P0712
The TFT is greater than 254°C (489°F) for
1 minute.
P0713
The TFT is less than -254°C (-425°F) for
1 minute.
Action Taken When the DTC Sets
• |
DTCs P0711, P0712, and P0713 are
Type B DTCs. |
• |
The TCM defaults to a calculated TFT 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
TFT sensor's output.

Circuit/System Verification
- Engine ticking over at operating temperature, verify
the scan tool Trans Fluid Temp. parameter is between -254 and
+254°C (-425 and +489°F).
- Operate the vehicle at 64 km/h (40 mph) for
10 minutes. Monitor the Transmission Fluid Temperature
parameter and the TCM Temperature parameter with a scan tool. The
Transmission Fluid Temperature parameter should increase by greater
than 2°C (3.5°F). Also, the Transmission Fluid Temperature
parameter and the TCM Temperature parameter should be within
20°C (36°F) of each other.
⇒ |
If the Transmission Fluid Temperature parameter
does not increase by greater than 2°C (3.5°F) or the
Transmission Fluid Temperature parameter is not within 20°C
(36°F) of the TCM Temperature parameter, then replace the Q8
control solenoid valve assembly. |
- After performing the above steps, verify that the DTC
does not reset by operating 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. If the vehicle passes the Circuit/System Verification
procedure then, refer to
Testing for Intermittent Conditions and Poor Connections .
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
