I'd have top check actual engine temp in degrees. If those are P codes, it's for 02 heater circuit.
If the battery is down, we can't do any testing. You either have to get it charged or get a new battery. Does the starter crank ok? If you use a digital multimeter across battery posts, key and everything turned off, what is the reading?
With the work you've done on it, possible air in the cooling system?
