Not a diagram but this should be pretty close to what your looking for and should have most sensor locations in it.

 

Here you go. Any questions ask. Have to pull air intake mixer pipe when pulling venturi tube to clean, so need new gasket where it bolts to cylinder head. Watch how you pull it out, can easily damage the rail pressure control valve connector (only did it once!). I have a brush that I clean venturi tube with first, then use scotch brite pad. I use pipe cleaners before blowing out the rifle drilled passages to the EGR delta P. The plugs are extremely tight and don't budge. The connector to EGR delta P sensor can be hard to get to, be gentle unlocking it. The temp sensor in intake manifold tends to seize in pretty good if hasn't been pulled in awhile. I use a little anti seize on it when reinstalling and they come out easy after that. DPF is exact same as Cummins.

 

That's dedication!!!
I only use contact cleaner sparingly on sensors, Napa Mac's 4710 electronic cleaner. On tubes I spray some Napa Mac's 8700 carb cleaner. On the intake mixer, I steam clean it with Landa heated pressure washer. Boost sensor is usually packed pretty well so I replace it. Go very easy with EGR delta P sensor, I usually just visually inspect and blow carbon loose with my lungs!
