Where is the oil sending unit located on a 2000 Dodge Caravan?

The oil pressure sending unit on a 2000 Dodge Caravan is located on the engine block, near the oil filter. It's a relatively small unit with one or two wires connected to it. You'll likely need to get under the vehicle to see it clearly. Because there are different engine options for the 2000 Caravan (3.0L, 3.3L, 3.8L), the exact position might vary slightly, but it's always in that general vicinity.
