DTC P0714:

ATF Temperature Sensor Circuit 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 Data List

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

YES -

Go to step 6.

NO -

Go to step 3.

3. Record the value of the ATF Temperature with the HDS in the A/T Data List.

4. Turn the ignition switch to LOCK (0), and wait for at least 30 minutes.

5. Compare the current ATF Temperature to the ATF Temperature recorded in step 3.

Did the ATF Temperature change?

YES -

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

NO -

Replace the ATF temperature sensor Testing and Inspection.

6. Record the values of the ATF Temperature and ECT Sensor 2 with the HDS.

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

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

YES -

Replace the ATF temperature sensor Testing and Inspection.

NO -

Intermittent failure, the system is OK at this time.
