DTC P0711: Problem in ATF Temperature Sensor Circuit
- Record all freeze data and review the General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ) before you troubleshoot.
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
- Check the ATF temperature with the HDS in the A/T data list.
Does the ATF temperature exceed an ambient-air temperature?
YES - Record the ATF temperature. Leave the engine off for more than 30 minutes, and go to step 2.
NO - Record the ATF temperature. Test the stall speed RPM (see STALL SPEED TEST ) three times. Go to step 2 after stall speed testing.
- Check the ATF temperature with the HDS.
Did the ATF temperature change?
YES - Leave the engine off for more than 30 minutes, and go to step 3.
NO - Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step 5.
- Check the ECT SENSOR with the HDS.
Is the ECT SENSOR equal to the ambient-air temperature?
YES - Go to step 4.
NO - Leave the engine off until ECT SENSOR equals ambient-air temperature, then go to step 4.
- Check the ATF temperature with the HDS.
Is the ATF temperature almost equal to ECT SENSOR?
YES - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ATF temperature sensor and PCM.
NO - Replace ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step 5.
- Clear the DTC with the HDS.
- Test-drive the vehicle for several minutes in the D position in all five gears.
- Check the OBD status in DTC Monitor Tool from DTCs/Freeze Data in A/T Mode Menu for a pass/fail test of code P0711.
Did the result indicate a pass?
YES - The problem has been corrected.
NO - Return to step 1 and recheck.
