    This truck has roughly 576k on it. When I come to a light or slow to a stop. The oil pressure drops all the way down and the red engine starts flashing saying engine shut off. If I give it gas in goes away. It normally runs between 25 to 30 psi at idle and 50 psi driving. Did a fresh oil change on the 4 of APR. Could it be a oil sensor. Please let me know guys. It has a DD15. Thanks Guys

    Could always be a sensor, but seeing as it came up when you stepped on the pedal I would say it's fine.
    Most common on that engine is the o-rings that go on the tubes from the oil suction manifold to the oil pump
    Must be changed really really soon, not an expensive job. Can even do it yourself.
