When I close the trunk it closes, but then i get the warning signal for open trunk after a minute or so.

It looks like the sensor is gone or something, so the lock keeps opening and closing all the time.

when driving over speed humps or similar bumps in the road, the warning stops momentarily.

Any suggestions on where the sensor is?

The sensor is part of the latch system, the only other sensor is for the light, and that is just a push button sensor on the frame of the car under the lid. Yo may want to try cleaning the latch, take some brake clean and a towel and spray it out thoroughly, then let it dry and lightly spray some WD 40 or equivalent in the mechanics. Also check to see if any of the bolts are loose and providing play in the latch.
