P0711

TX6A AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION SYSTEM: P0711; Transmission Fluid Temperature Sensor "A" Performance; 2013 MY FR-S [03/2012 -]
P0711 - Transmission Fluid Temperature Sensor "A" Performance

DESCRIPTION

The oil temperature sensor within the valve body detects the oil temperature within the transmission hydraulic control circuit, and inputs into the TCM a signal corresponding to the oil temperature.





MONITOR DESCRIPTION

This DTC indicates that there is a problem with output 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 TCM 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 TCM interprets this as a fault, and turns on the MIL.

INSPECTION PROCEDURE

1. DATA LIST

NOTICE:
* Perform the universal trip to clear permanent DTCs Reading and Clearing Diagnostic Trouble Codes.
* In the table below, the value listed under "Normal Condition" are reference values.

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 / ECT / Data List.

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





HINT
When DTC P0712 is output and Techstream output is -40°C (-40°F), there is a short circuit.

When DTC P0713 is output and Techstream output is 171°C (340°F), there is an open circuit.





PROCEDURE

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

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / ECT / Trouble Codes.

(e) Read the DTCs using the Techstream.

Result:





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

B -- GO TO DTC CHART TX6A Automatic Transmission
A -- Continue to next step.

2. CHECK TRANSMISSION FLUID LEVEL

OK:

Automatic transmission fluid level is correct.

NG -- ADD FLUID
OK -- Continue to next step.

3. READ VALUE USING TECHSTREAM (A/T Oil Temperature 1)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / ECT / Data List / A/T Oil Temperature 1.

(e) Read the value displayed on the Techstream.

Result:





B -- REPAIR OR REPLACE TRANSMISSION WIRE Removal
A -- Continue to next step.

4. REPLACE TCM

(a) Replace the TCM Removal.

NEXT -- PERFORM THE RESET MEMORY Programming and Relearning
