id050218818200

DTC P0741:00	TCC stuck off
DETECTION CONDITION	•  Under the following conditions, the difference between the engine speed and turbine speed is 100 rpm or more for 5 s. ―  Time since selector lever changing to D position is 10 s or more ―  Vehicle is driven without shifting ―  ATF temperature is 20 °C {68 °F} or more ―  Engine speed is 300 rpm or more ―  Turbine speed is 225 to 4,987 rpm ―  Vehicle speed is 62 to 96 km/h {38 to 60 mph} ―  Gear position is 4GR ―  TCC control is operated ―  Vehicle is driven in NORMAL mode ―  Shift solenoid A duty ratio is 99.22% or more ―  DTCs relating TR switch are not stored ―  DTCs relating input/turbine speed sensor are not stored ―  DTCs relating TFT sensor are not stored ―  DTCs relating shift solenoid A are not stored ―  DTCs relating shift solenoid B are not stored ―  DTCs relating shift solenoid C are not stored ―  DTCs relating shift solenoid D are not stored ―  DTCs relating shift solenoid E are not stored Diagnostic support note •  The check engine light does not illuminate. •  The automatic transaxle warning light illuminates if the PCM detects the above malfunction condition during the first drive cycle. •  PENDING CODE is not available. •  FREEZE FRAME DATA is not available. •  The DTC is stored in the PCM memory.
POSSIBLE CAUSE	•  Deteriorated ATF •  ATF level low •  Solenoid valve malfunction ―  Pressure control solenoid ―  Shift solenoid A ―  Shift solenoid B ―  Shift solenoid C ―  Shift solenoid D ―  Shift solenoid E •  Line pressure malfunction •  Control valve body malfunction •  PCM malfunction
