INSPECTION PROCEDURE
HINT:
According to the DATA LIST displayed by the hand-held tester, you can read the value of the switch, sensor
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
method to shorten labor time.
a. Warm up the engine.
b. Turn the ignition switch off.
c. Connect the hand-held tester together with the CAN VIM (controller area network vehicle interface
module) to the DLC3.
d. Turn the ignition switch to the ON position.
e. Push the "ON" button of the hand-held tester.
f. Select the item "DIAGNOSIS/ENHANCED OBD II/DATA LIST".
g. According to the display on tester, read the "DATA LIST".

DTC P0713 is output and hand-held tester output is -40°C (-40°F), there is an open circuit. Measure the
resistance between terminal OIL (OT) and body ground.
CHECKING CIRCUIT MALFUNCTION TABLE
HINT:
If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately set (in 0.5 second).
When P0713 is set, P0711 cannot be detected.
It is not necessary to inspect the circuit when P0711 is set.
1.INSPECT TRANSMISSION WIRE (ATF TEMPERATURE SENSOR)
a. Disconnect the transmission wire connector from the transmission.
b. Measure the resistance according to the value(s) in the table below.

DTC P0717: TURBINE SPEED SENSOR CIRCUIT NO SIGNAL
CIRCUIT DESCRIPTION
This sensor detects the rotation speed of the turbine which shows the input revolution of transmission. By
comparing the input turbine speed signal (NT) with the counter gear speed sensor signal (SP2), the ECM detects
the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure according to
various conditions. Thus, providin
g smooth gear shift.
