Your P0640 is the air intake heater nothing to worry about. actually you could remove the heater all together if you wanted and it wouldnt hurt the truck its there for emmissions. I have mine removed with delete plug with boost fitting for my boost gauge. The other code I don't know can't help you on that one. Welcome to Powerstroke.org
