Cheers.

First off thank you all for the suggestions/opinions. I appreciate it.

So I went back to the dealership/service center. We sat with the manager and the technician.

Basically they went step-wise changing parts that trigger P0128. As follows:
- Tstat
- Cooling system
- ECT sensor

Next in line...
The WIRE HARNESS

They walk me through those steps. Yes, CoryM that is what they are planning to do.

They showed me the factory white page of the wire and it is a hell of a job for such an error that a priori seems so innocent, I mean, it isn't that the car overheats or can't run!

Anyways... we reached a deal for parts cost only which I seemed fair.

This made me wonder of you guys driving your Yaris for over 100k miles... how much of this stuff you have to (or I will have to) go though only to keep this beautiful car.
