I would like to know where the Fuel Volume Regular Circuit is located on my DODGE 2005 Caravan.
Can anyone help?

Do you mean fuel pressure regulator?
It's on your fuel rail. Why are you needing this?
What are your vehicle's symptoms?

My CARMED device gives the following reading:

P00002 Fuel Volume Regular Circuit Low

This caused the Engine light to be on.

I'm sorry but that isn't even a valid Daignostic Trouble Code (DTC).
Please double check the code.
What else is the car doing? Any other symptoms with that light on?

I have one to many zeros in the code.
