You may need to "burp" the cooling system, possibly a number of times to ensure there are no air bubbles in it.

The water inside is probably a completely different issue. I say probably as there is a remote possibility of a heater core leak. More than likely it is water from a rainstorm or carwash etc. that works its way into the vent opening on the passenger side of the engine bay.

Causes for the P00B7 engine code may include:

Low coolant
Stuck thermostat
Defective ECT sensor
Faulty radiator coolant temperature sensor
Shorted or open circuits or connectors
Bad PCM or PCM programming error
