ISX 15 code spn 641 fmi 11
Have a 2016 Prostar with ISX 15 400ST, bone stock and have been getting this code thrown erratically lately. Truck seems to run fine and when it throws I will get the triangle on the dash warning engine light. Cycle the key and it goes away. What do I need to be looking for on this? Turbo actuator on the way out or spotty connection on the actuator harness? Truck has 492k miles on it.

Thanks.

I don't have insite, that was the pushing the cruise control on and resume button together. I thought I could pull them off with efi live and HD autocal but I could not. I have a neighbor that has insite if I need to have him do it.

spn641, fmi11 = I think that is Fault Code '2198'. VGT actuator root cause unknown.

Do a turbo inspection, re-calibrate it, etc.


Is this engine de-mandated (deleted)... if so then copy the program from the ecm and e-mail it to me for a review so that you know its not tearing up the turbo.
