• The Powertrain Control Module (PCM) compares the Crankcase Pressure Sensor Signal to the Mass Air Flow and Charge Air Cooler (Out) signals. The PCM sets this DTC if the rationality is above a calibrated threshold for 2.0 seconds. This is a two Trip Fault.
  
• I think your number is incorrect it should be p049db

Aftermarket air kits and boxes/programmers can trip codes.First step would be to contact banks.The dealer has no responsibility to deal with a banks product on your truck
