The tick-mark just before 210 °F = 182.5 °F. Your temperature dial should in-between these two. Mine never is. It’s always at 182.5 °F with a 195 °F thermostat. But that’s not important. What is important is that the CTS sends the correct information to the PCM. Since you just replaced your CTS, I would suspect that it is sending the correct information. I would not trust the read out of the dashboard display to be very precise. If you curious enough, you can check the resistance of the CTS at different temperatures using a pot of water on a stove with a thermometer. There are values for resistance vs temperature, listed in the Haynes manual. The best part about this test is it’s free. If you know how to plot graphs in Excel, then it does not matter what temperatures you choose. Simply plot your measured values and then co-plot the values listed in the Haynes manual. You will see if they are close or not. I would start if checking O2 sensor first.
