Oil pressure wiring diagram.

Anyone have one they could post. Got an lly with crazy oil pressure gauge, mechanic gauge reads good pressure 60+. Replaced the sending unit, now chasing wires. Also rebuild dash last week.

Hopefully these help. I might be able to pull some more, if you know what else to look for. This is all I could find right now.

Thank you, ended up being the 2 parts store OPS I tried. I went to gm and got a genuine Isuzu one and it worked

I have a 05 Lly that the oil pressure has dropped to zero and even stays at zero at high rpm but it still runs normal with no grinding or knocking and oil was just changed. Can anyone help me out?

Do you have a check oil pressure warning message on the dic? If not my guess is bad oil pressure stepper motor in the cluster

Try swapping in a gm oil pressure sender. That's what fixed the lly I was working on. And that was after the problem persisted after dash rebuild
