My light comes on when I am driving highway speeds. It never stays on long, 5 min or so and as soon as you turn the ignition off, it clears the code so I cant get a read on it. It happens when downshifting and accelerating to pass or pull a hill. Any ideas? I do have a superchips tuner installed but I have tried both with and without programming installed with the same results. Other than the light coming on, the truckruns fine. I have about 125k on it and this has also happened through 2 cam sensors.
I have the new controller. Just sent themmy old one and they sent me the new version. I will see if I can pull the code tomorrow. I know I could pull codes withthe old one but I never got a code for this scenario. I willpost what I find.
