Default vacuum leak detection unit worry

Someone stole the gas from my 2005 dodge caravan. I got an engine light code for gas cap issue. The cap had been put on incorrectly. So, I fixed it and had the codes cleared. Two days later, the code came back and autozone said maybe vacuum leak detection unit. The printout also still said gas cap. The gas cap is still on correctly, and my full tank of gas is still mostly full. Is the gas cap code always the gas cap, or is that code for many things? Can the vacuum leak detection unit be damaged by someone stealing your gas? Where is the unit?

What was the P code for the check engine light? You can get that by cycling the ignition key three times and leave in the run position on the third time.
