P0711

A760H AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM (for 4GR-FSE): P0711: Transmission Fluid Temperature Sensor "A" Performance
P0711 - Transmission Fluid Temperature Sensor "A" Performance

DESCRIPTION

P0712.





MONITOR DESCRIPTION

This DTC indicates that there is a problem with output from the automatic transmission fluid (ATF) temperature sensor (TFT 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 opens or shorts in the ATF temperature circuit or a fault of 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

NOTICE:
- Perform the universal trip to clear permanent DTCs Reading and Clearing Diagnostic Trouble Codes.
- If DTCs P0711 and P2610 are output simultaneously, confirm that the ATF temperature is as specified in "Normal Condition" using the Techstream first. When the ATF temperature is as specified in "Normal Condition", perform troubleshooting for DTC P2610 SFI System.
- In the table below, the value listed under "Normal Condition" are reference values.

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.

(a) Warm up the engine.

(b) Turn the engine switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the engine switch on (IG) position.

(e) Turn the Techstream on.

(f) Select the item "Powertrain / ECT / Data List".

(g) According to the display on the tester, read the "Data List".





HINT
When DTC P0712 is output and Techstream output is 150°C (302°F) or more, there is a short circuit.

When DTC P0713 is output and Techstream output is -40°C (-40°F), there is an open circuit.

Measure the resistance between terminal OIL and body ground.





HINT
If a circuit related to the ATF temperature sensor becomes 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.

PROCEDURE

1. CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P0711)

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG) position and push the Techstream main switch ON.

(c) When you use Techstream:

Select the item "Powertrain / ECT / Trouble Codes".

(d) Read the DTCs using the Techstream.

Result:





HINT
If any other codes besides "P0711" are output, perform troubleshooting for those DTCs first.

2. CHECK TRANSMISSION FLUID LEVEL

OK:

Automatic transmission fluid level is correct.

NG -- ADD FLUID

OK -- REPLACE TRANSMISSION WIRE
