    Hello forum. I hit the road this evening and about 3 miles later my low oil pressure warning light came on. Pulled over on the side of the highway and truck turned off. I didn't notice any oil leak when I did my pretrip inspection. I was able to drive the truck back but got that warning again twice. This is the code the truck gave:

    MID 128 PID 100 FMI 1

    Could this be a faulty oil pressure sensor, or is there an oil leak somewhere?

    Truck is a 2008 Volvo 780 with D13 and iShift Trans.

    Thank you in advance for the help. Be safe out there!

    Baha...first time I didn't notice. On the way back to park it, it was between 30 and 60. So between a quarter and half on the gauge. When. I was driving back I noticed too the gauge wasn't hitting 60 ( or half ) like it usually does while driving.

    MID 128 PID 100 - engine oil pressure
    FMI 1 - value too low.

    why is the next question.

    there's a link somewhere in the Volvo forum that has the chart for the codes.

    Oil Sensor is going south, when my went bad, it sprayed oil out of the sensor. What a mess that was.

    was it the oil level sensor or oil pressure sensor that went out on you? Sorry if that's a stupid question.
