where is the oil pressure sensor located @ and how much would it cost me to get on 2004 Isuzu Ascender

the oil gage stays all the way down past the 80 mark. but when i disconect the batery to reset it it goes back to normal @ 40 , and in about 4 to 5 days it drops again does that mean its the computer or the oil pressure sensor that can be bad..
