2000 Plymouth Voyager

I have a 2000 Plymouth Grand Voyager 3.3L V6 with about 90,000 miles on it. Recently after about 20-30 min of driving when I come to a stop the oil light comes on and a dinging noise sounds. Once the van starts to move again the light and ding both stop. It only does it when van is sitting idle after the engine is warm. Checked oil level and it is fine. Does anyone have a clue as to what it could be and how to fix it?
Thanks in advance.

Sounds like potential low oil pressure. Get it checked!
You need to hook up a pressure gauge and run it at thruway speeds to see the real pressure. Maybe it is just a bad sender, but you don't want to risk it. : Shock:

Update on status
Bad oil pressure sending unit so it was an easy fix. Thanks for the help. : )
