Ran the codes....
O.K. so I pulled the codes that the truck is throwing and I'm not real sure what they mean. I get a "12" code which I think means that the truck is in diagnostic mode, and then I get a "43" code which states "ESC Circuit" and "Knock Sensor". Anyone have any idea what this means and/or where I need to start to fix this problem?
