Circuit/System Verification

Note: Correct any engine controls and communication DTCs before diagnosing TCM DTCs.

1. DTC P0700 is an informational DTC. If there are no engine controls or communication DTCs, refer to Diagnostic Trouble Code (DTC) List -

Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle) for diagnosis of TCM DTCs.

2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

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

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

involved.
