DTC P0714 (6-Speed A/T)

DTC P0714  : ATF Temperature Sensor (Intermittent Failure)

NOTE: 

• Before you troubleshoot, review the General Troubleshooting Information - Refer to: How to Troubleshoot the A/T System .
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
• An engine block heater must not be used.

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.

   A/T System 

   Signal	Current conditions
   	Values	Unit
   ATF Temperature

   PGM-FI System 

   Signal	Current conditions
   	Values	Unit
   ECT SENSOR 2

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

   YES 

   Record the values of the ATF Temperature and ECT SENSOR 2 with the HDS, then go to step 3.

   NO 

   Go to step 2.

2. ATF 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 ATF Temperature to the ATF Temperature recorded in step 1-2.

   Signal	Current conditions
   	Values	Unit
   ATF Temperature

   Does the ATF Temperature change?

   YES 

   Leave the engine off for at least 6 hours, then go to step 3.

   NO 

   Replace the ATF temperature sensor .

3. ATF temperature sensor check

   - 1. Compare the values of the ATF Temperature and ECT SENSOR 2 with the HDS.

   A/T System 

   Signal	Current conditions
   	Values	Unit
   ATF Temperature

   PGM-FI System 

   Signal	Current conditions
   	Values	Unit
   ECT SENSOR 2

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

   YES 

   Replace the ATF temperature sensor .

   NO 

   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.
