DTC P0714: CVT Fluid Temperature Sensor (Intermittent Failure)
NOTE:
Before you troubleshoot, review the General Troubleshooting Information.
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

ECT SENSOR 2
    

Are the CVTF Temperature and ECT SENSOR 2 equal to the ambient air temperature?

     
YES
     
     
     
Go to step 3.
     
NO
     
     
     
Record the values of the CVTF Temperature, then go to step 2.
2.
Transmission fluid temperature difference check:

Transmission fluid temperature difference check
?1.
Turn the vehicle to the OFF (LOCK) mode, and wait for at least 30 minutes.

?2.
Turn the vehicle to the ON mode.

?3.
Compare the current CVTF Temperature to the CVTF Temperature recorded in step 1-2.

Did the CVTF Temperature change?

     
YES
     
     
     
Leave the engine off for at least 6 hours, then go to step 3.
     
NO
     
     
     
Faulty transmission fluid temperature sensor. Replace the solenoid wire harness.?

Is the value of the CVTF Temperature higher than the value of ECT SENSOR 2 by 58 °F (32 °C), or is the value of the CVTF Temperature lower than the value of ECT SENSOR 2 by 43 °F (24 °C)?

     
YES
     
     
     
Faulty transmission fluid temperature sensor. Replace the solenoid wire harness.?
     
NO
     
     
     
The transmission fluid temperature sensor is OK. Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the transmission fluid temperature sensor and the TCM. 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/onboard snapshot.?
