    This is the oil pressure at 1500rpm from an accurate gauge about 35psi.

    I replaced the oil pump and the oil filter housing and everything new that goes into the housing plus new cat oil filter and oil pressure picked up about 15psi but the oil light and buzzer still turned on this morning after about a 15 min drive. Anything else I can change out?

    Overhauled maybe 200,000 miles ago. Could a bad Iva oil pressure sensor cause this too?

    Not typically, but a leak in VVA's could. Kinda surprised it isn't throwing low VVA pressure code.

    So a leak in one of the vva solenoids could be causing it? Any way to check them?
