Code:

P0441 Evaporative Emission Control System Incorrect Purge Flow
or
Evaporative purge flow system not working properly 

My last code was October of 2006 with PO455 FUEL PUMP MODULE, which was replaced under warranty according to the dealer.
Today, this morning shortly after I started the jeep, i got the check engine light, and this time code is P0441.

P0441 is "EVAP purge system performance",could have a slow evap soliniod or and slow evap test pump.Either way you need to be hooked up to a DRBIII to be sure what is messing up forsure.

Have you been playing near the battery tray?? I had the same fault off and on for months, finally I saw the purge flow hoses disconnected (may have happened after the lift). It looked just like this:

I reconnected the hoses, and surprise surprise no more PO441 or PO440.

No, didn't play with the battery tray. I made an appointment with the dealer, i just want them to check it again.

Dealer said they will charge me $120 for the diagnostics only.
I said forget it. I am going to follow your suggestion and check the hoses tomorrow.

I played around with those hoses, the light was gone (or it stopped indicating) and after a week or so, now the light is back.
I cannot really spot the place you put on the illustration above. Does anyone have a picture of it's exact location? I don't want to be tugging and pushing wrong hoses.

The purge soliniod(labeled #1) in the pic is directly to the left of the battery(as looking at it),you should see a green cap on a evap line real close to it(about a inch or two).

Update, 42000 miles, the light is back. And it is P0441 again. No visual sign of damage, unless some piping or hoses are cracked..
I tried to locate the exact spot that is pictured on above illustration, I can't seem to find it! I can see some hoses there, but I don't see that post-like thing.. PS: I drove through over 2 feet of water once again the other day.

Make sure your gas cap is tight.

That's always the first thing I check and fiddle once I see check engine light. Next, I wait for this tank to finish just to see if it is bad gas.
