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 (see GENERAL TROUBLESHOOTING INFORMATION ).
- 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.
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
- 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 read the same as the ambient air temperature?
YES - Go to step 6.
NO - Go to step 3.
- Record the value of the ATF Temperature in the A/T Data List with the HDS.
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, and wait for at least 30 minutes.
- 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 (see ATF TEMPERATURE SENSOR REPLACEMENT ).
- Record the values of the ATF Temperature and ECT Sensor 2 with the HDS.
- 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 is 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 (see ATF TEMPERATURE SENSOR REPLACEMENT ).
NO - Intermittent failure, the system is OK at this time.
