What are troubleshooting codes P1684 and P0456?

P0456 is a small vacuum leak - see if you can trace down the vac lines for inspection according to the diagram that's on the sticker under the hood (it should be near the end of the hood prop on the covering over the radiator). I just took a picture of my 2002 Chrysler Town & Country but to get it small enough to upload you can't read the detail.

P1684 is an easily trigerred code that is from a diagnostic reader or battery issue - not 100% sure of it's cause but it does not trip the engine light.

Code P0456 on 2003 Town & Country

Below are the possible causes for your engine light and error code:

Possible Causes:
  • EVAP fuel tank or canister vapor hoses leaking or damaged
  • EVAP system component leaking, fuel cap loose or missing
  • Leak detection pump damaged or leaking

The fuel cap is probably the most common cause of this problem. It's considered part of the emission system and if faulty or not place on the filler tube correctly, it will throw an error. Best of luck with your engine light issue. Take care!
