Check engine light but no DIC code

Best Guess. Your local mehanic. Does not have the right codes for the scan tools. Because the manufactor holds them captive. You will have to go to a dealership to have the problem corrected. An reset the codes. Go in for an oil change. And and tell tell nothing about the light. When you get the car back. You should be OK. But These cars are made to make dealers money on service. Good Luck.

Problem solved.

A few weeks ago, I stopped at my mechanic's garage to get gas. The check engine light was still on. When I push the console button to unlock the gas door, the door did not open. With the mechanic helping me, we were able to prey the door open without damaging the car. I noticed the gas cap was not sealed tightly. After the gas filled the tank, sealed the cap, closed the gas door and started the car, the check engine light no longer appeared on the displayed (and the gas door not longer jammed).

I remembered then that the last time I got gas was at a "no name" station and not at my mechanic's station (my usual gas spot). Here in New Jersey we are not allowed to fill our own gas tank. I suspect the attendant at the "no name" did not sealed the cap correctly which produced the DIC check enging light error. For now on, I will get gas only at my mechanic's station.
