DTC P0714:ATF Temperature Sensor (Intermittent Failure)

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. When the engine is stopped and enough time has passed, the ATF temperature will equalize to the engine coolant temperature. When the temperature in the ATF temperature sensor deviates from the temperature in engine coolant temperature (ECT) sensor 2 after the engine is stopped and enough time has passed, the PCM detects a malfunction and stores a DTC.

[ ]: HDS Parameter

Malfunction Threshold
The temperature in the ATF temperature sensor deviates from the temperature in ECT sensor 2, less than -43 °F (-24 °C) or greater than 57 °F (32 °C)*.

*: Greater than 108 °F (60 °C) if engine block heater is equipped.

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
1.
Press the engine start/stop button to select the OFF mode in P, and wait for at least 6 hours.
2.
Start the engine in P, and wait for at least 10 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, the A/T gear position indicator blinks and a Confirmed DTC and the freeze data are stored. The MIL does not come on.

Conditions for clearing the DTC
The A/T gear position indicator comes off by pressing the engine start/stop button to select the OFF mode. The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
