DTC P0711 Transmission Fluid Temperature Sensor "A" Performance |
DESCRIPTION
The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid temperature into a resistance value which is input into the ECM.| DTC No. | DTC Detection Condition | Trouble Area |
| P0711 | (A) Both (a) and (b) are detected: (2-trip detection logic) (a) Intake air and engine coolant temperatures are more than -10°C (14°F) at engine start (b) After normal driving for over 19 min. and 8 km (5 mile) or more, ATF temp. is less than 20°C (68°F) (B) When engine coolant temp. is less that 35°C (95°F) at engine start, the ATF temp. is 110°C (230°F) or more after 17 min. of engine start (2-trip detection logic). | Transmission wire (ATF temperature sensor) |
MONITOR DESCRIPTION
The 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 ATF temperature circuit or a fault in the ATF temperature sensor.After running the vehicle for a certain period, the ATF temperature should increase. If the ATF temperature is below 20°C (68°F) after running the vehicle for a certain period, the ECM interprets this as a fault, and turns on the MIL.
When the ATF temperature is 110°C (230°F) or more after 17 minutes of engine cold start, the ECM also determines this as a fault, turns on the MIL, and stores the DTC.

INSPECTION PROCEDURE
| DATA LIST |
- HINT:
- Using the intelligent tester Data List allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the Data List early in troubleshooting is one way to shorten labor 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.
Warm up the engine.
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the ON position.
Turn on the tester.
Select the item "Enter / Powertrain / ECT / Data List".
Follow the instructions on the tester and read the Data List.
Item Measurement Item/
Range (display)Normal Condition A/T Oil Temperature 1 ATF Temp. Sensor Value/
min.: -40°C (-40°F)
max.: 215°C (419°F)Approx. 80°C (176°F) (After Stall Test) - HINT:
- When DTC P0712 is output and intelligent tester output is 150°C (302°F), there is a short circuit.
- When DTC P0713 is output and intelligent tester output is -40°C (-40°F), there is an open circuit.
- Measure the resistance between terminal THO1 (THO) and body ground.
Temperature Displayed Malfunction -40°C (-40°F) Open circuit 150°C (302°F) or more Short circuit - HINT:
- If a circuit related to the ATF temperature sensor become 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.CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P0711) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the ON position.
Turn on the tester.
Select the item "Powertrain / ECT / DTC / Current or Pending".
Read the DTCs using the intelligent tester.
- Result:
Display (DTC output) Proceed to Only "P0711" is output A "P0711" and other DTCs B
- HINT:
- If any other codes besides "P0711" are output, perform troubleshooting for those DTCs first.
