To be certain:
* Consult a repair manual: A Haynes or Chilton repair manual specific to your 1997 Chrysler Sebring 2.5L V6 will have diagrams showing the exact location of this sensor. This is the most reliable method.
* Visual inspection: Carefully look around the oil filter area on the passenger side of the engine. The sending unit will often be a small, cylindrical component.
* Use a parts diagram: Online auto parts websites (like AutoZone, Advance Auto Parts, etc.) usually allow you to look up parts diagrams for your specific vehicle. Enter your vehicle's details and search for "oil pressure sending unit" or "oil pressure switch." The diagram will show the location.
Remember to carefully inspect the area before touching anything, as engine components are hot after operation. Always disconnect the negative battery terminal before working on any electrical components.
