NO-Replace the ATF temperature sensor, then go to step 5.

3. 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 the ECT SENSOR reads the same as ambient-air temperature, then go to step 4.

4. Check the ATF TEMP SENSOR with the HDS.

Does the AT F temperature read about the same as the 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 the PCM.
