The oil pressure sending unit on a 1997 Dodge Ram 1500 5.2L V8 (Magnum) is located on the
driver's side (left) of the engine block, near the front. It's a relatively small unit, usually with a single electrical connector. You'll likely need to get under the truck to see it clearly. Be careful, as the engine will be hot if it's been recently run.
Because its location can vary slightly depending on specific engine configuration, it's best to consult a repair manual specific to your 1997 Dodge Ram 1500 5.2L. A diagram will pinpoint the exact location. You can often find these manuals online or at auto parts stores.
