Both times this has occurred was just after trailering. The truck doesn't run any different, it still runs just fine. I just have this CEL and whistle when I start it now. Going in to the dealership again Monday, going to have a long talk with them. Maybe they can tell me how to get the code. Question: Will this CEL ever clear itself if a condition is cleared or is it on until the dealer clears it? |
The pictures are there so if you can't see them they are probably being blocked by either a browser setting or a firewall setting. As for the Cel it all depends on the code whether it will go away or not. This is one of the reason most of us have at least an edge insight so we can see and clear the codes ourselves along with knowing when we go into Regeneration, Boost level and Exhaust Gas Temperture (EGT). If I knew what your code is I could look it up in my manual and we'd get a better idea of what's going on. The truth is that most of the Techs know less about these engines then we do because all they do is what the TSB or manual tells them to do.
The sliding Vane doesn't go by RPM. It works on load/Boost.
