2007 Dakota-"gascap" warning
I have a 2007 Dakota with 4.7 V-8. Gives "gascap" warning on dash display and ck. engine light is on. Have changed gas cap. What else could be causing this? Is it something a very mechanically inclined person can tackle without having to endure long waits and high rates at a dealership?

I have heard that buying anything other than the dealer supplied gascap can give headaches, but if it's not that then it's some other pressure loss in the tank I would think. These are some of the trickiest things to diagnose, between gascap and evap codes someone would eventually off themselves if they had to solve those for a living.

I have used and Advanced Auto one (broke the locking mechanism) and currently an Autozone one. I prefered the first one because it was an autolock style cap where as the new one is not. Check and make sure you didn't get a vented cap or that it is not in a vented mode, or two, make sure it is tight. I had the same issue when I bought my last cap. The reason was the cap had a vented mode and an unvented mode, which depended on whether the locking mechanism was depressed during locking or not. I made sure the cap was in the unvented mode and it has worked since and the code disappeared after the next start. Its definitely something with the new gas cap.
