Oil pressure gauge problems

[Bengy88]

What does insite say the oil pressure is? Always compare the readings in insite to the readings the truck is giving. If insite is reading low oil pressure I would pull a schematic for your engine and load test the wires to the sensor, you can do this by unhooking both sides of the circuit and wire a headlight to run off of the circuit, you want to make sure it is burning good and bright.
