Parktronic

Getting some intermittent false readings on the Parktronic system. Pulled the codes and there is a power supply issue. When watching the voltage for the system, it will go from 14 to 0v. Sometimes they are fine, other times I will get the front right indicator max out, other times the left indicator will max out. Sometimes it will be fine, other times it will just have two red indicators.

Where are the connectors for the sensors?
Is it a seperate power supply to the sensors, or is it just the battery power?

Aslo, how to tell how old the battery is? If I take a voltage reading after the car has sat for several days the voltage is 12.3 volts.
Thanks.
