Check Engine Light Always On
So my truck went into regen mode recently, and as always, the check engine light came on. Well, it has stayed on for 2 weeks and approx 1100 miles without any power loss or any other problems. I know this happens sometimes with these regen cycles on the DPF's, but how long should the light stay on in reality?
Would a DPF Delete Kit solve this problem (my main concern is that something really is wrong with the engine, but I wouldn't know it because the dealership said that the light is supposed to be for awhile)? Am planning on getting one soon anyway.
I don't feel like paying the dealership $150 to run the codes and end up resetting the ECM. Again.
Any help would be greatly appreciated!
