Where is the oil pressure sensor on a 1993 Dodge Dakota 3.9L V6?

The oil pressure sensor on a 1993 Dodge Dakota 3.9L V6 is located on the passenger side of the engine block, near the distributor. It's usually a small, somewhat cylindrical sensor. You might need to look carefully; it can be tucked in a bit. A shop manual or a detailed online diagram specific to that year and engine will give you the best visual confirmation.
