Just picked up an 06 LBZ, real clean truck that runs great and was well maintained. I noticed that the oil pressure gauge starts to bounce around intermittently on occasion, and the low oil pressure message will come up on the message board. Other than that the truck is running perfectly fine and I haven't seen or heard anything that seems unhealthy. I replaced the oil pressure sensor and that didn't fix the issue. I'm going to pick up a mechanical oil pressure gauge today and plug that in the verify for sure that the pressure is good. Anyone else run into this? And if so what was the fix?
