DTC P0713
DTC P0713: CVT Fluid Temperature Sensor (Open)
General Description
The transmission fluid temperature sensor is a thermistor type sensor that changes resistance according to the change in transmission fluid temperature. The powertrain control module (PCM) sends a 5 V reference signal to the sensor through a pull-up resistor. When the transmission fluid temperature is low, the sensor resistance increases and the PCM detects a high signal voltage. As the transmission fluid temperature rises, the sensor resistance decreases and the PCM detects a low signal voltage. When the transmission fluid 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 transmission fluid temperature sensor output voltage [CVTF 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.
- Transmission fluid temperature sensor TATF line open (includes connector loose connection or disconnection)
- Transmission fluid temperature sensor failure
- PCM internal circuit failure
Confirmation Procedure
Operating Condition
- Start the engine.
- Shift to P, 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, a Confirmed DTC and the freeze data are stored. The MIL does not come on.
Conditions for clearing the DTC
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.
