If you are asking if the engine will shut off when the sensor does not detect oil pressure, the answer is no. It will run without an oil pressure reading.
P1789-od/2-4 pressure switch circuit.
People have given all kinds of answers except the correct one. The most common reason for a stall is low oil pressure. The car has an oil pressure protection circuit that shuts down the motor when oil pressure gets below a certain level so that the bearings do not overheat. If the car stalls, then starts 10 to 15 minutes later, it is because the oil has cooled and thickened and has regained its pressure. Check the oil level. If you are 2 or more quarts low, the van will stall often as there are only 4.6 qts in the system and the protection circuit will kill the motor. Keep the oil at the correct level and this will not happen. The 1997 Caravan does NOT have an oil pressure protection circuit.
