oil gauge always on high on 2005 Nissan Pathfinder

when ignition is turned and car is running the oil guage needle goes up as far as it can go and stays there while engine is running.

Change the engine oil filter and oil pressure sender unit see if it solves the problem. If not verify oil pressure. 14 psi at idle should be more than 43 psi at 2000 rpm..
