Hello all, I was SO glad I was to run into this topic! My 2011 FFH has been having this exact same issue for several YEARS now. At first it was very infrequent, which made it frustrating because I couldn't "catch" it. And because it was so infrequent, despite finally one day catching an audio recording, the dealer had no idea what to do because they couldn't reproduce it. More recently it became far more frequent and the warning light started flashing (for the longest time all I'd experience was a five time "double chime." (Bing-bing, bing-bing, bing-bing, bing-bing, bing-bing." Sometimes three of them, sometimes four, but majority of times it was the five chime sequence. Recently this would happen 15-20 times during my morning and evening commutes. Driving me nuts! Even then, the local dealership service department couldn't (wouldn't) help, even after providing audio and video of it, because THEY couldn't see it happen. But enough about that. I'd searched previously and hadn't come across this invaluable string until recently. Having found it I printed it out, as others have, and took it to an independent service center with my video and photo, which they were willing to look at. They found the wires, as others have found, almost "destroyed" and the sensor was loose. The service man told me he used a multi-meter and found the sensor was shorting when he wiggled it (it had presumably come loose over time). They replaced: 1. The coolant temperature sensor (Motorcraft DY1144), an 2. Electrical connector (EC1680) and 3. Repaired the frayed wires, as another owner reported having done, rather than replace with another Ford wire bundle/assembly. Although I didn't see them, as someone else had suggested, it looks like Ford really made the wires just too short. Having read that post, I discussed it with my service team and we decided to "jump" the damaged wire segment with a longer segment of wire to reduce the chance that a new wire assembly would pull and tear, as the original had done. This might be something that others who might come across this consider doing with their mechanic. Overall, with parts and labor, in the Washington DC area, 11/2019, the cost was similar to what others have reported - I paid just over $400. I can't thank everyone who has posted on this topic enough!
