The carbon is on the intake valves, and needs a manual cleaning. Search here for a few threads on how to do it step by step....do NOT use a seafoam or similar as that causes damage when these hard particles are broken loose with engine running!!!
Then, even though the codes don't say MAF, that is a common series of codes for the MAF sensor failing except the fuel pressure code. That could be pressure sensor, but all of that is part of the HPDI pump. And when these pumps fail (rarely) it is usually the seals fail and it pumps raw fuel directly into the cylinder end and crankcase diluting the oil. So pull the dipstick and smell for strong gas smell.
Good luck!
