Subaru Crosstrek Service Manual: Dtc p0711 transmission fluid temperature sensor "a" circuit range/performance
CONTINUOUSLY VARIABLE TRANSMISSION (DIAGNOSTICS) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)
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
Diagnosis 1
• Detect the malfunction of the transmission 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
• Detect the malfunction of the transmission oil temperature sensor characteristics (stuck to high temperature side).
• Judge as NG when the difference between engine coolant temperature and CVT oil temperature is equal to or more than specified value at starting.
2. EXECUTION CONDITION
Secondary Parameters | Execution condition |
Diagnosis 1 | |
12 V battery system voltage | ≥ 10 V |
Engine speed (The timer is held when the following conditions are not satisfied.) | > 600 rpm |
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
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
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.

Fuel octane rating
Using a gasoline with a lower octane
rating can cause persistent and heavy
knocking, which can damage the engine.
Do not be concerned if your vehicle
sometimes knocks lightly when you drive
up a hill or when you accelerate. Contact
your SUBARU dealer if you use a fuel with
the specified oct ...
