Hoping to find some help. Got a vision 460 that runs good but at times while driving the shut down symbol will come on and truck just shuts down. Don't have a pattern to when it happens. stores 2 inactive codes. One is oil pressure sensor low circuit voltage and oil pressure below data valid but below operational condition. I replaced pressure sensor didn't make a difference cleaned engine grounds and oil pressure is between 15 and 20 at idle and around 50 to 60 under load. Does anyone know the pressure when the ecm shuts down? Has anyone dealt with problem. About 500 k on eng and problem just started out of the blue about a month ago.
