DTC |
P071015 |
Transmission Fluid Temperature Sensor "A" Circuit Short to Battery or Open |
DESCRIPTION
The ATF temperature sensor converts the automatic transaxle fluid (ATF) temperature into a resistance value for use by the ECM.
The ECM applies voltage to the temperature sensor through terminal THO1 of the ECM.
The sensor resistance changes with the ATF temperature. As the temperature rises, the sensor resistance decreases.
One terminal of the sensor is grounded so that the sensor resistance and voltage decrease as the temperature rises.
The ECM calculates the ATF temperature based on the voltage signal.

MONITOR DESCRIPTION
This DTC indicates an open or short to +B in the ATF temperature sensor circuit. The ATF temperature sensor converts the ATF temperature into an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature, and can detect an open or short in the ATF temperature sensor circuit. If the resistance value of the ATF temperature sensor is higher than 156 kΩ*, the ECM interprets this as a malfunction of the ATF temperature sensor or in the wire harness, illuminates the MIL and stores this DTC.
*: -40°C (-40°F) is indicated regardless of the actual ATF temperature.
HINT:
The ATF temperature can be checked in the Data List.

CONFIRMATION DRIVING PATTERN
HINT:
- After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
-
When clearing the permanent DTCs, refer to the Clear Permanent DTC procedure.

![2020 - 2024 MY Camry [03/2020 - ]; UB80F (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: DTC CHECK / CLEAR](/t3Portal/stylegraphics/info.gif)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for 2 minutes or more.
- Turn the ignition switch to ON and turn the Techstream on.
- Start the engine.
-
Wait for 10 minutes or more with the engine running. [*1]
HINT:
[*1] : Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Transmission / Utility / All Readiness.
- Input the DTC: P071015.
-
Check the DTC judgment result.

DATA LIST
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.
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.
(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 / A/T Oil Temperature No.1.
(g) Read the Data List according to the display on the Techstream.

-
If DTC P071015 is output and the Techstream indicates -40°C (-40°F), the circuit is open.
Check the temperature displayed on the Techstream in order to check if a malfunction exists.
