2015 coyote fault code P0116

My MIL illuminated and indicated P0116 - engine coolant temp sensor 1 circuit range performance

I have become friendly with a tech at Ford tech support and I asked him about this. He actually indicated that this is a known issue and there is a coolant temp software issue that is causing this in the crate motors. Apparently when they get the factory PCM they diet a lot of stuff out of the production version of the pcm. Somewhere along the way this caused an issue and there is a software update for this.
I was given the option of sending my PCM to them to flash with an update or they could send me a device to upload a software fix through the OBD port. So if anyone gets this code in the future call Ford for a software update. Dont try to trouble shoot it with other methods.

Scott,
If you do not mind would you put this post in your build thread. I am building a very similar car and might encounter similar problems. I might forget this issue and not find the separate thread, when the time comes.

Thanks,

good idea. It is in there now.

Scott I seem to be getting this code as well with my 2017 Gen2. I didn't read any codes previously when I checked, but I am seeing the P0116 when I checked just now. I also have a symptom that may be related. On a cold start, the engine fires up fine, but it then quickly drops RPM as if it is going to stall out, then it revs back up and all seems fine. On a warm start this never happens, just cold. Did they end up sending you a device to flash the PCM or is it going to require it to be pulled? I have a custom tune so I assume I would have to reload the tune afterwards? Thanks

Nope. Never saw this DTC with my Gen 3.

They sent me a device to correct the issue. However Paul and I had made friends with the guy at the tech line and I think he did that as a favor. He is no longer in that position and I believe shortly after they told others they would not send the device out any longer. People with that issue would be required to send it in. Details are a little fuzzy as it has been a few years but I think that is how it went.
Paul if that is incorrect please correct me.

That's exactly how it went.
