DESCRIPTION
The No. 2 ATF temperature sensor is installed in the transmission valve body assembly.
If the ECM detects an abnormally high ATF temperature near this sensor, it illuminates the warning indicator.
HINT:
Vehicle conditions when the sensor is normal and when the sensor is short-circuited are indicated in the table below.
No. 2 ATF Temperature Sensor State |
Detection Condition |
Symptom |
Recovery Condition |
---|---|---|---|
Sensor is normal |
ATF temperature higher than 150°C (302°F) |
ATF temperature warning indicator remains on |
ATF temperature below 135°C (275°F)*1 |
ATF temperature higher than 130°C (266°F) |
Shift point too high |
ATF temperature below 110°C (230°F) |
|
Sensor is short-circuited |
Any conditions |
Shift point too high |
Symptoms still occur |
Engine coolant temperature higher than 95°C (203°F) |
Lock-up at 3rd gear*2 |
Symptoms still occur |
HINT:
*1: When ATF temperature is in the normal range, it decreases to below 135°C (275°F) within 5 minutes with the shift lever in P or N in an idling state.
*2: When ATF temperature is normal, transmission lock-up occurs in 4th, 5th and 6th gear with the shift lever in D or with the S6 range selected, in 4th or 5th gear with the S5 range selected, and 4th gear with the S4 range selected.

MONITOR DESCRIPTION
The No. 2 ATF temperature sensor converts the ATF temperature to an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature and detects a short in the No. 2 ATF temperature sensor circuit. If the resistance value of the No. 2 ATF temperature sensor is below 25 Ω*, the ECM interprets this as a fault in the No. 2 ATF temperature sensor or wiring. The ECM stores the DTC.
*: 150°C (302°F) or higher is indicated regardless of the actual ATF temperature.
HINT:
The ATF temperature can be checked on the Techstream display.

Refer to DTC P071011 (See page ).
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 / Transmission / Data List.
(g) According to the display on the Techstream, read the Data List.

No. 2 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. 2 ATF temperature sensor circuit is open or shorted. |
HINT:
Check the temperature displayed on the Techstream in order to check if a malfunction exists.
