First, you need to check the engine oil level. If it is low, top it off to the specified amount on the dipstick. If the level is normal, you may have a bad pressure switch that is simply not reading correctly. Another issue I have seen on your vehicle is the oil pump pick up tube (this is the part that carries oil to the oil pump) The rubber o ring fails and the pump can't pull the oil up the tube which in turn drops your oil pressure. I do not recommend running your engine until it is determined, whether or not you have oil pressure. Running an engine even for a short period without oil pressure can cause serious internal damage. I suggest having a qualified technician to inspect and repair the oil pressure issue.
