P0713
DTC P0713 TRANSMISSION FLUID TEMPERATURE SENSOR "A" CIRCUIT HIGH INPUTCIRCUIT DESCRIPTION
DTC Detecting Condition:
The ATF temperature sensor converts fluid temperature into a resistance value which is input into the ECM.
MONITOR DESCRIPTION
Monitor Strategy:
Typical Enabling Conditions:
Typical Malfunction Thresholds:
Component Operating Range:
The automatic transmission fluid (ATF) temperature sensor converts ATF temperature to an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects opens or shorts in the ATF temperature circuit. If the resistance value of the ATF temperature is less than 79 Ohm*1 or more than 156 kOhm*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM turn on the MIL and store the DTC.
*1: 150 °C (302 °F) or more is indicated regardless of the actual ATF temperature.
*2: -40 °C (-40 °F) is indicated regardless of the actual ATF temperature.
HINT: The ATF temperature can be checked on the OBD II scan tool or hand-held tester display.

INSPECTION PROCEDURE
HINT: According to the DATA LIST displayed by the OBD II scan tool or Hand-held tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a 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 OBD II scan tool or Hand-held tester to the DLC3.
d. Turn the ignition switch ON.
e. Push the "ON" button of OBD II scan tool or Hand-held tester.
f. Select the item "/DIAGNOSIS/ENHANCED OBD II/DATA LIST/ALL (or ATM)".
g. According to the display on tester, read the "DATA LIST".
HINT: When DTC P0712 is output and OBD II scan tool or hand-held tester output is 150 °C (302 °F), there short circuit.
Measure the resistance between THO1 (THO) and body ground.
