Let's start with the ECT sensor issue. I suspect this is most likely a faulty sensor. However, we need to figure this out and then address the other issues as I doubt they are related. In fact the ECT issue is probably not related to the overheat as it wouldn't make the engine overheat.
So we need get a little more detail about these issues. Was this vehicle sitting for a while? Was there more to this or was the vehicle driving fine just before this and you decided to change the battery?
Let's start with this info and we can go from there. Thanks
