Subaru Legacy Service Manual: Dtc p0711 transmission fluid temperature sensor "a" circuit range/performance

DTC DETECTING CONDITION:

Detected when two consecutive driving cycles with fault occur.

TROUBLE SYMPTOM:

Excessive shift shock

Shift characteristics malfunction

NOTE:

For the diagnostic procedure, perform the diagnosis according to DTC P0712 and P0713. Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0712 TRANSMISSION FLUID TEMPERATURE SENSOR "A" CIRCUIT LOW Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0713 TRANSMISSION FLUID TEMPERATURE SENSOR "A" CIRCUIT HIGH

1. OUTLINE OF DIAGNOSIS (ENGINE TYPE FB)

Diagnosis 1

Judge the malfunction of oil temperature sensor characteristics (stuck to low temperature side).

Judge as NG if the amount of oil temperature change since ignition ON is equal to or below the predetermined value.

Diagnosis 2

Judge the malfunction of oil temperature sensor characteristics (stuck to high temperature side).

Judge as NG when the difference of engine coolant temperature and CVT oil temperature exceeds the predetermined value both when starting engine and when driving.

2. EXECUTION CONDITION (ENGINE TYPE FB)

Secondary Parameters

Execution condition

Diagnosis 1

12 V battery system voltage

≥ 10 V

Transmission range

Drive

Vehicle speed (calculated from secondary pulley shaft speed)

≥ 21.9 MPH

Diagnosis 2

12 V battery system voltage

≥ 10 V

Engine coolant temperature at the end of the previous drive cycle − Engine coolant temperature at engine start

≥ 40 degC

3. DIAGNOSTIC METHOD (ENGINE TYPE FB)

If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.

Judgment Value

Malfunction Criteria

Threshold Value

Diagnosis 1

Absolute change of measured Transmission fluid temperature sensor input voltage

< 0.049 V

Transmission fluid temperature

< 20 degC

Diagnosis 2

Transmission fluid temperature − Engine coolant temperature at engine start

> 46 degC

Time Needed for Diagnosis:

Diagnosis 1: 600 s

Diagnosis 2: 300 s

Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.

4. OUTLINE OF DIAGNOSIS (ENGINE TYPE EZ)

Diagnosis 1

Judge the malfunction of oil temperature sensor characteristics (stuck to low temperature side).

Judge as NG if the amount of oil temperature change since ignition ON is equal to or below the predetermined value.

Diagnosis 2

Judge the malfunction of oil temperature sensor characteristics (stuck to high temperature side).

Judge as NG when the difference of engine coolant temperature and CVT oil temperature exceeds the predetermined value both when starting engine and when driving.

5. EXECUTION CONDITION (ENGINE TYPE EZ)
