Answers :

The Thermo Sensor valve would be the next place to look. Since the EGR valve is ok, and your experiencing temp problems, the Thermo Sensor would make sense. Below is a diagram showing the layout and where the valve is. Before removing or replacing, check all the vacuum lines for leaks. It's possible the components are good but a pinhole in a vacuum line could throw a check engine light. Best of luck.
