When you say “ i have a nock sensor going off ” are you saying you can here a knocking sound or are you referring to the knock sensors not working? If you can hear a knocking sound about 2 K revs with low oil pressure than I would guess the big ends are on their way out. Remove the oil filter and open it up, if it looks like the one below than I'm afraid its big ends and possibly the crank have had it.
