P0713
DTC P0710: Malfunction of Transmission Fluid Temperature SensorDTC P0712: Malfunction of Transmission Fluid Temperature Sensor (Short)
DTC P0713: Malfunction of Transmission Fluid Temperature Sensor (Open)
NOTE: When using general scan tool.
DIAGNOSTIC FUNCTION
TCM conducts fault detection by monitoring the terminal voltage of the transmission fluid temperature sensor.
^ [P0710, P0712]: If transmission fluid temperature equals or exceeds specified value, TCM judges that transmission fluid temperature sensor has a failure.
^ [P0710, P0713]: If transmission fluid temperature is below specified value even after test driving for more than the specified period, the TCM judges that the transmission fluid temperature sensor has a failure.
DESCRIPTIONS OF MONITOR METHODS [P0710,P0712]
^ TCM detects the fluid temperature 180 degrees C (356 degrees F) or more for 5 seconds.
MONITOR EXECUTION [P0710, P0712]
^ Continuous
MONITOR EXECUTION CONDITIONS (OTHER MONITOR AND SENSOR) [P0710~P0712]
Other Monitor (There is no temporary DTC stored in memory for the item monitored below)
^ P0741: Abnormality in lockup function
^ P0746: Abnormality in hydraulic control system function
^ P0841: Abnormality in line pressure sensor function
Sensor (The sensor below is determined to be normal)
^ Not applicable

Ignition switch : ON (start the engine and keep it for 10 seconds or more)
DESCRIPTIONS OF MONITOR METHODS [P0710, P0713]
^ TCM detects the fluid temperature -40 degrees C (-40 degrees F) or less for five seconds.
MONITOR EXECUTION [P0710, P0713]
^ Vehicle speed 10 km/h or more has been detected during 1 drive cycle
MONITOR EXECUTION CONDITIONS (OTHER MONITOR AND SENSOR) [P0710, P0713]
Other Monitor (There is no temporary DTC stored in memory for the item monitored below)
^ P0741: Abnormality in lockup function
^ P0746: Abnormality in hydraulic control system function
^ P0841: Abnormality in line pressure sensor function
Sensor (The sensor below is determined to be normal)
^ Not applicable
LOGIC FLOW CHARTS (Monitor Sequence) [P0710, P0713]
DTC SET CONDITIONS [P0710, P0713]
Check Conditions
^ After vehicle speed: 10 km/h (6.2 mph) or more.
^ Voltage of battery: 9 volts or more.
^ Voltage of battery: 16 volts or less.
Judgment Criteria
^ Value of temperature of transmission fluid: -40 degrees C (-40 degrees F) or less. (5 seconds)
OBD-II DRIVE CYCLE PATTERN [P0710, P0713]
transmission range: D (Drive the vehicle for 10 seconds or more while the accelerator opening angle is 20% or more)
PROBABLE CAUSES
^ Malfunction of the valve body assembly (Faulty transmission fluid temperature sensor)
^ Damaged wiring harness and connectors
^ Malfunction of TCM
DIAGNOSTIC PROCEDURE
STEP 1. M.U.T.-III data list
Item 5: Transmission fluid temperature sensor signal (Refer to Data List Reference Table Data List Reference Table).
Q: Is the check result normal?
YES: Intermittent malfunction
NO: Go to Step 2.
STEP 2. Check the following connector:
^ B-08 Transmission assembly connector
^ C-40 TCM connector
^ A-09 Intermediate connector
Check the terminals for a contact status problem and internal short circuit.
Q: Is the check result normal?
YES: Go to Step 3.
NO: Repair the defective connector.
STEP 3. Check for open circuit and short to ground in the wiring harness between the CVT assembly connector and the TCM connector
Between B-08 CVT assembly connector (terminal No. 17) and C-40 TCM connector (terminal No.50)
Q: Is the check result normal?
YES: Go to Step 4.
NO: Repair the wiring harness.
STEP 4. Check for open circuit in the wiring harness between the CVT assembly connector and the TCM connector
Between B-08 CVT assembly connector (terminal No. 19) and C-40 TCM connector (terminal No.48)
Q: Is the check result normal?
YES: Go to Step 5.
NO: Repair the wiring harness.
STEP 5. Transmission fluid temperature sensor check
Refer to [1][2]Testing and Inspection.
Q: Is the check result normal?
YES: Go to Step 6.
NO: Replace the valve body assembly.
STEP 6. Symptom recheck after erasing diagnosis code
Q: Is the check result normal?
YES: Intermittent malfunction
NO: Replace TCM.
