Engine codes
I have the following codes just popped up on my truck I’ve done some googling on it and it doesn’t totally explain what’s going on with my truck. Does anybody know where I can get a full complete list of codes and what they are for my exact model of truck? Or at least for now answer me on what these codes mean exactly I’m gonna post some pictures. Right now I’m leaning towards crank case ventilator and intake pressure sensor. Thanks in advance!
