DTC P0710: Malfunction of Transmission Fluid Temperature Sensor
DTC 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.

PROBABLE CAUSES



DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III data list
Item 5: Transmission fluid temperature sensor signal (Refer to Data List Reference Table ).

Q. Is the check result normal?
Intermittent malfunction
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?
Go to Step 3.
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?
Go to Step 4.
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?
Go to Step 5.
Repair the wiring harness.

STEP 5. Transmission fluid temperature sensor check
Refer to .

Q. Is the check result normal?
Go to Step 6.
Replace the valve body assembly.

STEP 6. Symptom recheck after erasing diagnosis code

Q. Is the check result normal?
Intermittent malfunction
Replace TCM.
