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 400-7,500 RPM for 5 s.
• Ignition voltage is 9-32 V.
• Accelerator position signal is valid.
• Engine torque signal is valid.
• Brake torque is not active.
• DTC runs continuously when above conditions are met.

P0712

• DTC P0712, P0716, P0717, P0722, or P0723 is not set.
• Engine speed is 400-7,500 RPM for 5 s.
• Ignition voltage is 9-32 V.
• DTC runs continuously when above conditions are met.

P0713

• DTC P0713, P0716, P0717, P0722, or P0723 is not set.
• Engine speed is 400-7,500 RPM for 5 s.
• Ignition voltage is 9-32 V.
• DTC runs continuously when above conditions are met.

Conditions for Setting the DTC

P0711

• TCM detects a 20-50ºC (36-90ºF) 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 20-50ºC (36-90ºF) 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 min within a 6 min period.

P0712

Transmission fluid temperature is 254ºC (489ºF) or greater for 1 min.

P0713

Transmission fluid temperature is -254ºC (-425ºF) or less for 1 min.

Action Taken When the DTC Sets

• 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

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. During a road test, the transmission fluid temperature should steadily increase to a normal operating temperature, and then stabilize.

Circuit/System Verification

1. Engine idling at the normal operating temperature.
2. Verify the scan tool Transmission Fluid Temperature parameter is between -254 and +254ºC (-425 and +489ºF).

If not between -254 and +254ºC (-425 and +489ºF)

Replace the Q8 Control Solenoid Valve Assembly.

If between -254 and +254ºC (-425 and +489ºF)

3. Verify the scan tool Transmission Fluid Temperature parameter increases greater than 2ºC (3.6ºF) after operating the vehicle at 64 km/h (40 mph) for 10 min.

If the temperature does not increase greater than 2ºC (3.6ºF)

Replace the Q8 Control Solenoid Valve Assembly.

If the temperature increases greater than 2ºC (3.6ºF)

4. Verify the scan tool Transmission Fluid Temperature and the TCM Temperature parameters are within 20ºC (36ºF).

If the temperatures are not within 20ºC (36ºF)

Replace the Q8 Control Solenoid Valve Assembly.

If the temperatures are within 20ºC (36ºF)

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 the DTC sets

Replace the Q8 Control Solenoid Valve Assembly.

If the DTC does not set

7. All OK.
