P0711
| Transmission Fluid Temperature
Sensor Circuit-Range/Performance
| B
|
| • | DTC P0711 is stored in PCM history |
| • | If any engine coolant temperature sensor codes are set, then the
transmission defaults to a temperature of 132°C (269°F) |
| • | If the engine coolant temperature is greater than 115°C (239°F),
then the transmission will default to a temperature of 132°C (269°F).
This will enable Transmission Hot Mode. The transmission remains in Hot Mode
until the engine coolant temperature drops below 110°C (230°F). If
the engine run time is less than 3 minutes, then the transmission defaults
to the intake air temperature at ignition ON. |
| • | If the engine coolant temperature is between 45°-115°C
(113°-239°F), then the transmission default temperature equals ECT - 10°C
when the intake air temperature is less than 27°C (81°F) at ignition
ON. If the intake air temperature is greater than 27°C (81°F) at ignition
ON, then the transmission default temperature equals ECT + 10°C. |
| • | If the engine run time is greater than 3 minutes and the
engine coolant temperature is less than 45°C (113°F), then the transmission
default temperature is 12°C (54°F) |

then the transmission will default to a temperature of 132°C (269°F).
This will enable Transmission Hot Mode. The transmission remains in Hot Mode
until the engine coolant temperature drops below 110°C (230°F). If
the engine run time is less than 3 min, then the transmission defaults
to the intake air temperature at ignition ON. |
| • | If the engine coolant temperature is between 45°-115°C
(113°-239°F), then the transmission default temperature equals ECT - 10°C
when the intake air temperature is less than 27°C (81°F) at ignition
ON. If the intake air temperature is greater than 27°C (81°F) at ignition
ON, then the transmission default temperature equals ECT + 10°C. |

engine coolant temperature is less than 45°C (113°F), then the transmission
default temperature is 12°C (54°F) |

ON. If the intake air temperature is greater than 27°C (81°F) at ignition
ON, then the transmission default temperature equals ECT + 10°C. |
| • | If the engine run time is greater than 3 minutes and the
engine coolant temperature is less than 45°C (113°F), then the transmission
