Code P2744 Description

The ATF (Automatic Transmission Fluid) Temperature Sensor converts the fluid temperature into a resistance value. The sensor resistance changes with the transmission fluid temperature. As the temperature becomes higher, the sensor resistance decreases. The Transmission Control Module (TCM) monitors the ATF (Automatic Transmission Fluid) Temperature Sensor signal. The TCM sets the OBDII code when the ATF (Automatic Transmission Fluid) Temperature Sensor signal is out of factory specifications.
