Edit: What does your aftermarket coolant temp sensor tell you the temperature of the coolant is when the engine is cold? It should read around the same temperature as the ambient temperature.

Yes, you're correct, but since these parts aren't cheap. It's a waste to me when the result is the same, is all. If the issue is resolved or somewhat different, at least purchasing whatever item did something. There's still a list of things to check.
The coolant temps read fine.

this log shows a cold start, very first of the day. Ambient temps are around 75F and coolant temps are 68F. it was like 10am or something like that and car was in the shade.
