So I went through all the threads and never did find anything conclusive
2019 with slight mods
Banging through the desert on second day of a run and dummy oil pressure gauge drops to zero, low oil pressure pops up on display and goes to limp mode. Pull over, check oil and it's barely below top line. Restart truck and it's fine. Turn on real oil pressure gauge display and jump back onto course. This happens another ten times over the next few hours at all different throttle levels with the dummy gauge showing zero and the real gauge showing fine going into limp mode. It actually even fixed itself a couple times without turning off motor. Checked oil again at gas station after run and still showing pretty much full. Drove home through Death Valley and around town the last week and a half with no issues.
Truck has 23,000 miles of which I'd guess 3,000 hard off road.
This happened once early this year and a couple times in Baja in March. I took it to dealership in April and they said they could see the code but no reason for it and could not determine problem without duplicating it. I called and talked to them again and they said pretty much so the same thing. Bring it in and we'll try and diagnose it but if we can't replicate it we won't do anything. It has only happened once on pavement and the chance it will do it for them seems slim, like driving down there is a waist of time.
Truck does not leak oil or even burn it for that matter as I've never added more than half a quart near end of oil cycle.
The only thing I can think of is check the connection and wire for damage.
If the dummy gauge and real gauge read from the same sending unit, is it possible it could be in the gauge cluster?
