DTC P0714: ATF Temperature Sensor (Intermittent Failure)
WARNING: This page is about a different car, the 2013 Honda Odyssey, 2012 Honda Odyssey, and 2011 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review 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).
- 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 parameters of 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.
- 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 recheck the ATF Temperature again with the HDS.
Does the ATF Temperature change?
YES -Leave the engine off for at least 6 hours, then go to step 4.
NO -Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ).
- 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.
- 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 more, or the value of the ATF Temperature Sensor lower than the value of ECT Sensor 2 by 43°F (24°C) or more?
YES -Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ).
NO -Intermittent failure, the system is OK at this time.
