DTC P0711
DTC P0711: ATF Temperature Sensor (Range/Performance)
General Description
The ATF temperature sensor is a thermistor type sensor that changes resistance according to the change in ATF temperature. The powertrain control module (PCM) sends a 5 V reference signal to the sensor through a pull-up resistor. When the ATF temperature is low, the sensor resistance increases and the PCM detects a high signal voltage. As the ATF temperature rises, the sensor resistance decreases and the PCM detects a low signal voltage. If the ATF temperature sensor signal does not change, the PCM detects a malfunction and stores a DTC.

[ ]: HDS Parameter
Malfunction Threshold
Stuck at low temperature
The current ATF temperature [ATF TEMPERATURE] is -4 deg.F (-20 deg.C) or less after Enable Conditions.
Stuck at high temperature
The current ATF temperature [ATF TEMPERATURE] is 230 deg.F (110 deg.C) or more after Enable Conditions.
Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- ATF temperature sensor failure
- PCM internal circuit failure
Confirmation Procedure
Operating Condition
Stuck at low temperature
- 1.
Start the engine with the engine coolant temperature [ENGINE COOLANT TEMPERATURE] at 95 deg.F (35 deg.C) or less.
- 2.
Warm up the engine until the engine coolant temperature [ENGINE COOLANT TEMPERATURE] reaches 158 deg.F (70 deg.C) or more.
- 3.
Drive the vehicle at a speed of 19 mph (30 km/h) or more with the throttle position at 4 deg. or more for at least 5 minutes.
- Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
Stuck at high temperature
- 1.
Turn off the engine with the engine coolant temperature [ENGINE COOLANT TEMPERATURE] at 158 deg.F (70 deg.C) or more.
- 2.
Start the engine after the engine coolant temperature [ENGINE COOLANT TEMPERATURE] drops to 95 deg.F (35 deg.C) or less.
- 3.
Warm up the engine until the engine coolant temperature [ENGINE COOLANT TEMPERATURE] reaches 158 deg.F (70 deg.C), and wait for at least 20 seconds.
With the HDS
None.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, a Confirmed DTC and the freeze data are stored. The MIL does not come on.
Conditions for clearing the DTC
The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
