DTC P0713: ATF Temperature Sensor (Open) (DCT)
General Description
The ATF temperature sensor is a thermistor type sensor that changes resistance according to the change in ATF temperature. The powertrain control module (PCM) sends a 5 V reference signal to the sensor through a pull-up resistor. When the ATF temperature is low, the sensor resistance increases and the PCM detects a high signal voltage. As the ATF temperature rises, the sensor resistance decreases and the PCM detects a low signal voltage. When the ATF temperature sensor signal voltage to the PCM is above specification, indicating that the temperature is below specification (open), the PCM detects a malfunction and stores a DTC.

[ ]: HDS Parameter
Malfunction Threshold
The ATF temperature sensor output voltage [ATF Temp Sensor (V)] is more than 4.93 V for at least 10 seconds.
Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- ATF temperature sensor TATF line open (includes connector loose connection or disconnection)
- ATF temperature sensor failure
- PCM internal circuit failure
Confirmation Procedure
Operating Condition
Start the engine in P position/mode, and wait for at least 10 seconds.
With the HDS
None.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
