The second code for thermostat monitoring is most likely just a result of the voltage on the Coolant Temp Sensor being out of range...... this is nothing to be alarmed about.
+1. When temp. sensor goes out, or any sensor for that matter, it shuts the circuit which causes a too high resistance (blocked circuit-way due to the bad sensor) which cause the CEL show.

Just have dealer change it and you should be all set! Let us know how things works out for you.
