Could be the gas cap. Do you fill the tank with the engine running?
Otherwise, check the hoses near the Evap canister. I have 2003 T&C and had the small leak and large leak codes. I looked at the evap cansiter and the hose coming from the fuel tank vapor line had a huge crack in it, to the point it had fallen off the evap caniser. I trimmed the end of the hose and reconnected and voila, no codes.
The evap canister is on the driver's side of the van, underneath, slightly behind the drivers seat.
BTW, to clear the codes without an OBDII reader, remove the negative cable for 5-10 minutes (15 to be safe). The computer resets and clears the codes, except for one that it sets saying loss of power to the memory.

I had the same problem, could not figure it out. Looked all over the inter net found a post that said something about the ground wire that had a bad connection. So i followed the found wire and this is what i found. attached photos, plus whati did to fix it.
