Default Oil pressure switch screen

Anybody know if an 03 6.0 has this ?
My oil pressure goes to 0 @ idle all of a sudden .
Changed oil , sender. Etc
Now it's 5-10 lbs @ idle . Motor is dead quiet
I'm thinking it's the cluster since gauge used to bounce . Changed sender was ok for a while . Then this . Fuel gauge goes in and out . Read online about the screen but couldn't see with a cheap inspection camera . Unless it's down deep ?

Is this on a 03 truck by chance? If it is it's about 99.00% chance it's the cluster itself. It's a very common problem.

Trucks an 02 . It’s got a 7 gauge cluster . I ordered one from Texas cluster . Hopefully it’s the gauge and not the o ring . I can’t see it just going bad .

No screen on non AFM engines. Check pressure using mech gauge. Tap into galley port on left side of engine below PS pump or rear of oil filter. M16x1.5 adapter needed.

99 up full size trucks have gauge issues, I have an 03 that I replaced the cluster twice now and my 09 has never had a working oil pressure gauge since I bought it 5 years ago, I replaced the sending unit and it didn't fix it....it's a 4.8 so I don't really care, I just change the oil and if it does eventually have a problem with the engine it will get upgraded to a 5.3 or 6.0, They never should have put a 4.8 in a these trucks.

Put a harbor freight gauge on it . Same ****
Pulled the pan , changed o ring
Same **** . It will go to 40 if I rev it
But 0 on start up then 45 sec later
10 lbs @ idle on gauge ( cluster )
Gonna try some sea foam then change oil
Put 20/50 Mobil 1 . really sucks . Motor is quiet
It's weird . I can get an 06 with 100k
For 1100 supposed to be 24x
