Circuit Description

WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: This diagnostic procedure is for manual transmission vehicles with RPO VD1 and/or RPO Z06.

The transmission fluid temperature (TFT) sensor contains a semiconductor device which changes the resistance based on the temperature, a thermistor. The TFT sensor has a signal circuit and a ground circuit. The powertrain control module (PCM) applies a voltage, approximately 5.0 volts, on the signal circuit to the sensor. The PCM monitors the changes in this voltage caused by changes in the resistance of the sensor in order to determine the fluid temperature.

When the PCM senses a signal voltage higher than the normal operating range of the sensor, DTC P0713 sets. DTC P0713 is a type C DTC.
