Yes, the ECU logic is that if it commands the EGR valve to open, after a period of time, the temp. sensor should indicate a temperature inside the EGR valve above some minimum value to tell the ECU that hot exhaust gas is indeed flowing through the valve. If not, the ECU assumes with the sensor or the valve is not working.
