DTC P0714:

ATF Temperature Sensor Intermittent Failure

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information 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.

1. Turn the ignition switch to ON (II).

2. Check the following parameters with the HDS:

- ATF Temperature in the A/T Data List.
- ECT Sensor 2 in the PGM-FI SYSTEM Data List

Are the ATF Temperature and ECT Sensor 2 about the same as the ambient air temperature?

YES -

Go to step 4.

NO -

Go to step 3.

3. Check the ATF Temperature with the HDS in the A/T Data List, and record the ATF temperature. Turn the ignition switch to LOCK (0), wait for 30 minutes, and check the ATF Temperature with the HDS again.

Does the ATF Temperature change?

YES -

Leave the engine off for more than 6 hours, then go to step 4.

NO -

Replace the ATF temperature sensor Testing and Inspection.

4. Record the values of the ATF Temperature in the A/T Data List and ECT Sensor 2 in the PGM-FI SYSTEM Data List with the HDS.

5. Compare the values of the ATF Temperature Sensor and ECT Sensor 2.

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

YES -

Replace the ATF temperature sensor Testing and Inspection.

NO -

Intermittent failure, the system is OK at this time.
