change oil pressure sensor first to eliminate that. if that dont work could be oil pump and or loose bottom pully bolt. or blocked oil pump strainer.
first off oil and filter change try this if dont work change oil pressure sensor.
Hi Brian,
Sorry to hear about this. Do you have any more details as to what it could be apart the warning light? Could be something as simple as a sensor?
Although it doesn't sound good I wouldn't write it off yet.
