Dodge Caravan 2003 P1684 P0442 P0455 P0456

Check engine light came on a couple of weeks ago. At first it was just the battery code P1684 and the small evap code P0442. Now the other two codes are showing as well. What are the chances that this is only a gas cap issue? I just replaced the cap but have not driven it yet. Since I am getting all the codes I am guessing there is a pretty good chance I have a leak. Still holding out hope that it is just the cap.

I have the same thing going on with my 2002 Town & Country 3.8L.
Please share if the new gas cap fixed your problem?

My situation had a weird coincidence involved that makes me wonder if related...
2 weeks ago (before check engine light came on), I was at a gas station filling up. While the gas nozzle was in the car pumping gas, I absent mindedly pushed my keyfob to open the automatic left rear sliding door. It unlatched (only allowing the door to move about an inch, coming nowhere even close to contacting the gas nozzle), and then relatched and closed itself. Thank goodness that failsafe is built in.
I then drove the car about 5 miles home, and I didn't notice the check engine light on during that drive (but not to say it didn't come on right then, with a van full of children distracting me). The next day when I drove the van, I immediately noticed the check engine light.
Autozone scanned it for me, and told me P0456. I checked that the gas cap was tight, unhooked the battery to clear codes, and the next day or so the check engine light came back on.
I haven't gone back to Autozone yet, but rather did the "key to ON position and off 3 times", and this resulted in the odometer giving me the codes P1684, P0442, P0455.

Seems like quite a coincidence that my check engine light came on at or within 5 miles of attempting to open the rear sliding door with the gas nozzle in the fuel tank...?

I took mine to the shop and so far they haven't found anything wrong with any hoses. They claim that the new gas cap was not on tight. So the jury is still out. If it is not the cap they are thinking there might be some type of vacuum seal issue? I haven't searched the forums yet to find any info on this. Hoping the problem can be resolved quickly. Need to get it fixed so I can pass emissions!

Back from the shop, light has been turned off. I am hoping it stays that way but I am betting it will come back on. A little annoyed that they only did a visual inspection of hoses and not a smoke test. They said they will do one if the light comes back on. There is a thread on this page that was helpful that involves these codes.

jcole2424-- I don't know if you are following this thread, but my engine light just came back on so I don't think it is the gas cap. Thought I was in the clear, but no. Ugh.

Sorry to hear that. Was hoping the silence in this thread meant that you had resolved the issue. Well, thankfully I have a year before I have to take mine through DEQ testing. So thanks for your update, and keep them coming! :-)

Glad to know I am not talking to myself! I got the van back from the shop again. They replaced a hose after a smoke test. Not sure of the location, the service detail just says evap hose. The part is $20. I paid $123 with parts, labor, and smoke test. I hope this takes care of it. The codes that came up the second time were P1684 and P0455.

Just found this video online that might be helpful to you. I hope the shop I took my vehicle to was this thorough. http://www.youtube.com/watch?v=CSn0ljUS ... ata_player

My 2001 dodge caravan is running like it has a miss. I recently replaced one of the O2 sensor about 3mths ago. Now the van runs with a miss and hesitates until I push the gas. I found a broke clamps on the evap valve under located under the van below the driver seat. That seem to help a little NOT the problem, but still misses. I looked at the gas cap because codes are reading P0442 P0171 & P0455, it needs replaced I think it is dry roughted. I let you know if it works. Going after the fuel filter next. then the evap valve.
