Chrysler have a common problem with the Natural Vacuum Leak Detection system. A switch fails and the computer flags the failure. Google "Chrysler NVLD" lots of information on line. The fix usually requires replacing the NVLD assembly but the evaporation emission control system should be properly checked before just replacing components.

I have had the same problem and the same code. I changed my gas cap. It(engine light)went off for a week and has been on since (for about a year). It's time for inspection and now I need to repair shift solenoid and find emission leaks.

OMG! I just had the same nightmare about the transmission work to the tune of 2500.00. The car wasn't shifting. I have to go through inspection too and my engine light is still on after a year. Did they find the leaks? Was it very costly? Is it an extensive job? Mo' Money, Mo' Money...

Actually it ended up being the ERG valve. It was stuck in the closed position. Got a new one and cleaned up the lines - presto! Thanks to all who answered.

I have a '06 Pacifica 3.5L. At about 140K miles 'ck eng' light/'gas cap' alert on odometer came on. Computer had codes P0440 and P0442 (Evap system) stored. Replaced gas cap w/Chrsler cap...no good. Ended up (at 169K) replacing pass side secondary fuel pump and the plastic evap line that goes between secondary and primary (left side) fuel pumps. Seems the line shrinks over time/miles and starts pulling sideways on it's fitting, causing the fitting to crack/break triggering the two alerts. Since it is all one molded piece on top of pump, you can't replace fitting only the pump. As a side note Chrysler has not changed the design of this pump so an owner could conceivably have the same prob again in the future. Of course the tank has to be dropped. Personally, this is the only vehicle I've seen with two fuel pumps. The secondary pump is actually a transfer pump to move fuel in tank to keep fuel flowing from right side to left side. I paid $493, but the normal rate would prob be $700/$800. The shop will recommend both pumps be replaced (the shop should do this, for their business, but also to eliminate the possiblility of having to do primary pump later if needed and paying more $$$-if needed.) After repairs done 'ck eng/'gas cap' alert lights went out and car was able to pass emission test. I also have rocker/lifter noise in my engine, started about 10K ago.

I LOVE THIS CAR. I HAVE 230,000 MILES ON IT AND THE CHECK ENGINE LIGHT HAS BEEN ON SINCE 2007. THE CAR RUNS LIKE A DREAM. THE ONLY PROBLEM IS, IT WON'T PASS INSPECTION. I HAVE THE CARBON ERROR AND LAST YEAR THE GARAGE CHANGED THE EVG VALVE AND THE LIGHT STAYED OFF FOR 2 DAYS. AFTER 2 DAYS IT CAME ON AND IS ON STEADY EVER SINCE. I GET 20MILES TO THE GALLON AND THIS APPEARS TO BE A DESIGN FLAW WITH CHRYSLERS COMPUTER. EACH YEAR IT IS COSTING ME MORE AND MORE TO PASS INSPECTION.CHRYSLER DISCONTINUED THIS CAR. (BEFORE PEOPLE COULD SUE THEM FOR THE MAINTAINENCE.)
