That is the Delta P sensor calibration.
Check that the Delta P sensor isn't cracked on the bottom plate from the ehat that comes off the engine. Then check to see if it is plugged.
Usually when I get this code, I replace the Delta P because it has soot clogging it, then I do a Delta P Counts calibration with the Detroit softtware.
Either way, the Detroit software is needs to calibrate it so it is easier to replace it and then have it calibrated to prevent a come back.
