Where is the oil sending unit on a 96 dodge Dakota?

The oil pressure sending unit on a 1996 Dodge Dakota is located on the engine block, near the oil filter. It's usually a small, cylindrical unit with one or two wires connected to it. You'll likely need to get under the truck to see it clearly. Because there are several variations of the 3.9L and the 5.2L engines in that year, the exact location might vary slightly, but it will always be in close proximity to the oil filter.
