Where is the oil sending unit on a 1988 dodge Dakota 3.9L?
The oil pressure sending unit on a 1988 Dodge Dakota 3.9L is located on the driver's side (left side) of 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 look closely and possibly use a flashlight to spot it, as it can be somewhat tucked away.
