CHECK DTC OUTPUT (IN ADDITION TO DTC P0711)
CHECK TRANSMISSION FLUID LEVEL
DTC P0711 Transmission Fluid Temperature Sensor "A" Performance
DESCRIPTION
Refer to DTC P0712 ().
| DTC Code | DTC Detection Condition | Trouble Area |
| P0711 | Either condition is met (2-trip detection logic): (a) Certain monitor enabling conditions are met and the ATF temperature is below 20°C (68°F). (b) Certain monitor enabling conditions are met and the ATF temperature is 110°C (230°F) or higher. | No. 1 transmission wire (No. 1 ATF temperature sensor) |
MONITOR DESCRIPTION
This DTC indicates that there is a problem with the signal from the Automatic Transmission Fluid (ATF) temperature sensor and that the sensor itself is defective. 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.

INSPECTION PROCEDURE
| DATA LIST |
- HINT:
- Using the intelligent tester 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.
Warm up the engine.
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Powertrain / ECT / Data List.
According to the display on the tester, read the Data List.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| A/T Oil Temperature 1 | No. 1 ATF temperature sensor value/ Min.: -40°C (-40°F) Max.: 150°C (302°F) | After stall test: Approximately 80°C (176°F) With engine cold: Equal to ambient temperature | If the value is -40°C (-40°F) or 150°C (302°F), the No. 1 ATF temperature sensor circuit is open or shorted. |
- HINT:
- When DTC P0712 is stored and the intelligent tester output is 150°C (302°F) or higher, there is a short circuit.
- When DTC P0713 is stored and the intelligent tester output is -40°C (-40°F), there is an open circuit.
- Check the temperature displayed on the tester in order to check if a malfunction exists.
| Temperature Displayed | Malfunction |
| -40°C (-40°F) | Open circuit |
| 150°C (302°F) or higher | Short circuit |
If a circuit related to the 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.
| 1.CHECK DTC OUTPUT (IN ADDITION TO DTC P0711) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Powertrain / ECT / Trouble Codes.
Read the DTCs using the tester.
| Result | Proceed to |
| Only P0711 is output | A |
| P0711 and other DTCs are output | B |
- HINT:
- If any other codes besides P0711 are output, perform troubleshooting for those DTCs first.

| 2.CHECK TRANSMISSION FLUID LEVEL |
Check the transmission fluid level ().
- OK:
- Automatic transmission fluid level is correct.
