Wow looks like it could be fun because I suck at electrical issues.

Have a look through this sticky , it may give you some idea's , the vacuum system can be hard to chase down some leaks.
good luck , i had problems with the PVH solenoid some years ago, i ended up fitting a new one only to find it wasn't the problem, so go through the info and see what you find and report back.

Just a coincidence, the ESOF has no connection with the turbo or pedestal, so after you have gone through the sticky you will have a better idea of what your looking at.

Hub unit seals are a common leak area, especially if you've regreased the needle roller bearings without renewing the yellow o-ring on the hub.

I have had a faulty PVH solenoid before.

New truck and it also throws the P1876 code.

Once again appreciate this thorough thread on how to diagnose.

When this code P1876 is reported, should my Transfer Case still switch between 2H-4H-4L ?
Because mine shifts to each of these and back out of them to 4H.

Will a leaking ESOF throw this code? I think thats how I made it go away last time.

Thanks
