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.

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.

Checking the coolant level
WARNING Never attempt to remove the radiator cap until the engine has been shut off and has cooled down completely. Since the coolant is under pressure, you may suffer serious burns from a spray of boiling hot coolant when the cap is removed. "FULL" level mark "LOW" level mark C ...
