DTC P0711

DTC P0711  : ATF Temperature Sensor (Range/Performance)

NOTE:
DTC Description Confirmed DTC Pending DTC Freeze Frame
P0711 ATF Temperature Sensor (Range/Performance)      

DTC (A/T)

  1. Current ATF temperature check

    -1. Turn the vehicle to the ON mode.

    - 2. Check the parameter(s) below with the HDS.

    Signal Threshold Current conditions
    Values Unit Values Unit
    ATF Temperature Less than - 4 °F    
    Less than - 20 °C

    Do the current condition(s) match the threshold?

    YES 

    Go to step 2.

    NO 

    Go to step 3.

  2. ATF temperature sensor check (after warm up)

    -1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).

    - 2. Check the parameter(s) below with the HDS.

    Signal Threshold Current conditions
    Values Unit Values Unit
    ATF Temperature Less than - 4 °C    
    Less than - 20 °F

    Do the current condition(s) match the threshold?

    -4 °F (- 20 °C) or below

    Replace the ATF temperature sensor .

    Abnormal temperature rise

    If there is an abnormal temperature rise in temperature of the ATF temperature sensor, update the PCM if it does not have the latest software , or substitute a known-good PCM - Refer to: How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the A/T System (2014 2015), .

    -4 °F (- 20 °C) or higher

    The ATF temperature sensor is OK. Intermittent failure, the system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

  3. Problem verification

    -1. Check the parameter(s) below with the HDS.

    Signal Threshold Current conditions
    Values Unit Values Unit
    ATF Temperature More than 230 °F    
    More than 110 °C

    Do the current condition(s) match the threshold?

    YES 

    The failure is duplicated. Go to step 4.

    NO 

    Intermittent failure, the system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

  4. ATF temperature sensor check (after cool down)

    -1. Let the engine cool until the Engine Coolant Temperature reads 122 °F (50 °C) or below with the HDS.

    Signal Current conditions
    Values Unit
    Engine Coolant Temperature    

    - 2. Check the parameter(s) below with the HDS.

    Signal Threshold Current conditions
    Values Unit Values Unit
    ATF Temperature More than 230 °F    
    More than 110 °C

    Do the current condition(s) match the threshold?

    230 °F (110 °C) or higher

    Replace the ATF temperature sensor .

    Abnormal temperature decrease

    If there is an abnormal temperature decrease in temperature of the ATF temperature sensor, update the PCM if it does not have the latest software , or substitute a known-good PCM - Refer to: How to Troubleshoot the A/T System (2014 2015), or How to Troubleshoot the Fuel and Emissions Systems, .

    230 °F (110 °C) or below

    The ATF temperature sensor is OK. Intermittent failure, the system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.
