Trouble code P1684 means: The battery has been disconnected within the last 50 starts . and p0455 is evaporative emission control system,( large leak )-- how to fix--try by either loosening gas cap or tightening it to see if this is where the leak is! most of the time it is the cap..

P0455 Evaporative Emission Control System Leak Detected (gross leak) - check your entire engine bay contents for any type of leak, air conditioner when it's running, coolant, things like that.
P1684 Battery Disconnected Within Last 50 Starts - this is a code that will go away over time

Yes, the P1684 on the Chrysler line does not indicate a fault. My sebring had codes p0442 and p0456 both indicating very small evep leaks. When I did the 3 time switch on of the ignition, the odometer readout gave me the p1684 first and then the other two. The scanner at the garage only indicated two "very small evap leaks" one for the second two codes. Clearly the first is a status indicator such as recent battery disconnect or another non problematic indicator. Wouldn't it be great if these manufacturers at least gave you the information to identify what their dummy lights are telling you so you didn't have to go on faith at the garage?
SOURCE: What is the trouble code p1684, and p0455.
1684 is 'battery disconnected in last 50 starts' and should shut off after you have used it for 50 more.
0455 is 'Evaporative emission control system leak detected (gross leak)

I just got P0551 too..looks like you need to get a new switch ($30 from autozone)

P0442: EVAP leak monitor medium (.040). Leak detected.
P0455: EVAP leak monitor large. Leak detected.
P0456: EVAP leak monitor small (.020). Leak detected.
I suggest check the lines and flow it down to the ldp (leak detection pump) that is just behind the steering gear under the van It has a wire connector and 2 large EVAP hoses. look for any split or crack then follow the lines back to the tank. Even a small crack is a leak.
Hope helped with this. Remember rated this help. Good luck.
Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, and/or
Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary
