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.
