Is a factory crimp. There are many like that on other circuits throughout the loom.
EDIT:
A lot of what I said was already said/asked.
I would suggest plugging everything in as it was, and hooking that orange wire up as it was to the ECU. Start from scratch.
Withkey on/engine off, monitor the coolant temp sensor as you unplug the sensors on that circuit:
Throttle position sensor
Intake air temp sensor
Both O2 sensors
EGR boost sensor
the fuel tank pressure sensor is hopefully not at play, but that'll be under the fuel pump access hatch beneath the back seat.
If that doesn't do it:
Start unplugging the rest of the sensors too. At some point, whatever is causing issues will not be in the circuit, and the ECU will either stop saying "HOTTTTTTTTTTTTTT" or there will be no change...
