Question type: Maintenance & Repair

I have a 2010 Dodge Grand Caravan that the check engine light has stayed on for the last 3 days. I just came from
the dealer and they said it gave a trouble code B2394. They didn't really explain what it meant. Can you help?

Get the codes read again. Write the number down. The B2394 is not a valid code. P2394 is not valid either.

The code was printed out from the machine. It says B2394. What it says next ti it is this. " Flash to pass/ Optical horn swith circuit stuck. The reason I took it to the is because the engine light was staying on. The code from that was P0456. I know thats for a vaccum leak. It gave that code before and the did a smoke test and said they found the leak and fixed it. Now it gives the same code and they told me the leak is on top of the gas tank from one of the lines. How could that happen on a vehicle that's only 3 years old. It's out of warranty also but I do still have the powertrain warranty.
