DESCRIPTION
The No. 1 ATF temperature sensor converts the fluid temperature into a resistance value for use by the ECM.
The ECM applies a voltage to the temperature sensor through terminal THO1 of the ECM.
The sensor resistance changes with the ATF temperature. As the temperature becomes higher, the sensor resistance decreases.
One terminal of the sensor is grounded so that the sensor resistance decreases and the voltage goes down as the temperature becomes higher.
The ECM calculates the fluid temperature based on the voltage signal.

The output voltage from the ATF temperature sensor is higher than 4.91 V for 0.5 sec. or more, and either condition is met (1 trip detection logic): (A) 600 sec. or more have elapsed after the engine start when engine coolant temperature or intake air temperature is -29.375°C (-20.875°F) or less. (B) 10 sec. or more have elapsed after the engine start when engine coolant temperature and intake air temperature are higher than -29.375°C (-20.875°F). |

MONITOR DESCRIPTION
The No. 1 ATF temperature sensor converts the ATF temperature to an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature and detects an open or short in the No. 1 ATF temperature sensor circuit. If the resistance value of the No. 1 ATF temperature sensor is below 79 Ω*1 or higher than 156 kΩ*2, the ECM interprets this as a fault in the No. 1 ATF temperature sensor or wiring. The ECM will illuminate the MIL and store the DTC.
*1: 150°C (302°F) or higher 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 Techstream display.

CAUTION / NOTICE / HINT
NOTICE:
HINT:
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
1. DATA LIST
HINT:
Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / Engine and ECT / Data List.
(g) According to the display on the Techstream, read the Data List.

Diagnostic Note |
---|---|---|---|
A/T Oil Temperature 1 |
No. 1 ATF temperature sensor value/ Min.: -40°C (-40°F) Max.: 150°C (302°F) |
|
If the value -40°C (-40°F) or 150°C (302°F), No. 1 ATF temperature sensor circuit is open or shorted. |
HINT:
When DTC P0712 is output and the Techstream indicates 150°C (302°F) or higher, there is a short circuit.
When DTC P0713 is output and the Techstream indicates -40°C (-40°F), there is an open circuit.
Check the temperature displayed on the Techstream in order to check if a malfunction exists.

HINT:
If the circuit related to the No. 1 ATF temperature sensor becomes open, P0713 is immediately stored (in 0.5 seconds). When P0713 is stored, P0711 cannot be stored.
It is not necessary to inspect the circuit when P0711 is stored.
