Code P0713 Cadillac Description

The Automatic Transmission Fluid Temperature (TFT) sensor is a resistor, or thermistor, which changes value based on temperature. The sensor has a negative temperature coefficient. This means that as the temperature increases, the resistance decreases, and as the temperature decreases, the resistance increases. The transmission fluid temperature sensor is located inside the Transmission Control Module assembly which has no serviceable parts. The transmission fluid temperature sensor provides transmission fluid temperature information to the Transmission Control Module. This fault is handled inside the Transmission Control Module and no external circuits are involved.
The Diagnostic Trouble Code (DTC) will be set if the transmission fluid temperature is 174°C (345°F) or greater for 1 min.
