oil pressure guage is sky high. I have changed the oil already on 1995 Mitsubishi Eclipse

The pressure guage for the oil is sky high. what do i do?

Asked by for the 1995 Mitsubishi Eclipse
Did you change the oil filter? I think I would put a mechanical gauge in place and verify pressure or just change the sender unit to see if oil gauge the reads correct, I looked and couldn't find a spec for oil pressure, oil pressure relief valve could be stuck but it would be nice t know with a mechanical gauge what the oil pressure is.
