But the gas cap is well closed, I checked it twice.
Do you have any idea what else it could be? :(

On your DIC there is a mode at which you can set the speed limit on your car, if you go over that speed limit an alarm will sound. You may have accidentally turned this feature on. Read your owners manual and it will tell you if this has been activated or how to check it.

The computer must run all tested a few more times and detect no problems before the light will reset on it's own. But if you are worried just go see the dealer and let them pull codes for you and reset the light.

That's excatly what happened. I went to the dealer and he pull codes and reset the light.

The car didn't run when I used key remote because of the Engine light ON (According to my dealer info).

There is no Engine Alarm now.

Thanks guys

I thought I knew about all there is to know about these new engines but one of my buddies who is a master tech said when you pump gas , once the pump cuts itself off do not keep pumping that last little bit in because it will mess up the carbon cannister and set off this same light. I had no idea. Maybee this is common knowledge, but ive built many of these engines and never heard anything like this

Thats true, you shouldn't "top off" the gas tank. Doing so can fill the evaporative emissions system (charcoal canister, leak detection pumps, etc) with gas and cause all kinds of problems, check engine lights, and even cause the engine to die while your driving around. I've fixed a few Chryslers that had this problem of dying, due to fuel in the evap system.
Of course, it doesn't happen to everyone, but it can.

This is all correct info. It just happened on my wife's Grand Prix a few weeks ago. The car will not start with the auto start feature when the check engine light is on. Just found that out when this happened to the Grand Prix.
