Check Engine Light S90-V90

I have read the code, p0442, and I am aware that it means a leak in the emissions evaporative system, most likely a loose or defective gas cap.

I also understand that I can erase the code with my reader after fixing it.

My question is on this car, will that code reset itself and turn the light off eventually when the problem is fixed? How else would I know if I solved the problem other than resetting it and seeing if it comes on again?
