Mass air flow sensor code, pull the sensor and clean it with Mass Air Flow Sensor cleaner first, then check the crankcase ventilation system, clean or replace defective components, clear the codes and start it up, if the code returns then the sensor could be bad or you have fresh air leaks in the intake tubing. If the blow by is now gone then you have fixed your problem there but it not then you have internal engine problems, rings, pistons, cylinder walls.
If you're getting a puffing type of blow by, with the engine running, the head gasket has blown into the crankcase. Jim
