The oil pressure switch on a 2004 Chrysler Sebring 2.7L is located on the
driver's side of the engine block, near the oil filter. It's a relatively small sensor. You'll likely need to get under the car or use a mirror to see it clearly.
Be aware that some variations exist due to engine specifics and minor model differences, so a picture online of a 2.7L engine from a similar year Sebring might be helpful to confirm its exact location.
