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.

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.

Engine low oil level warning light
This
light illuminates when the engine oil
level decreases to the lower limit.
If the engine low oil level warning light
illuminates while driving, park the vehicle
in a safe and level location, and then
check the engine oil level. When the
engine oil level is not within the normal
rang ...
