My 08' Ford edge overheated the other day while idling for 15 min. The coolant overflowed and emptied and I got a P1299 error code. I thought it might be the thermostat but I checked the ECT and the radiator didn't start heating up till after 180ºF. After the temp got over 205ºF one fan kicked on but even with the A/C on the second fan never kicked on. I ran the car for a while idling and the temp never got about 216ºF even with some revs. Am I dealing with a cooling fan replacement or the temp sensor? Does anyone have suggestions on what to check next? I checked the fuse (no towing package) and the fuse in the hood fuse box was fine.
