I pulled these 3 codes today U0219, P0403, and U0407. I can't find any info on the U0219, the others I have founf and my EGR is unplugged. I have a 2005 F-250 CC 4X4 6.0L. Any info would be great. Thanks Scott
The door switch is part of the latch that holds the door closed. I am guessing you have the door ajar light on when the doors are closed? If so spray WD40 in the latch liberally and open/shut the door a few times.
Well the guys at HMP being the great guys they are found it. I unpluged the seatbelt conector sometime ago and that is what was giving me the code. I guess. Thanks for your help.
U codes are for comunication between module on the CAN network. some are normal and will not cause you MIL to illuminate. some tuners will cause U codes and will not affect the truck at all. the P0 codes you had are from the EGR circuit and will cause the mil to be illuminated.
