06 DTS hood jar light keeps coming on???

Ok guys, I have always been a sports car guy but the other day I bought a 2006 DTS with 60k on her. The car seems to be great but over the weekend the hood jar/ hood open popped up on the dash. So I pulled over and check the hood and it was good and closed. So I opened it and slam it and took off again. Less than a minute later the light came back on. Later I tryed looking for some kind of sensor around the hood hinge and the latch. I didnt have any luck but there was some kind of connecting plug right below the hatch. Any help here guys? Also now my remote start won't work. I'm guessing due to the hood light being on?
