I cleared the code and ran the truck a good bit and the check engine light has stayed off. I checked again and the code is correct but it seems to be very uncommon just my luck, the only thing i can figure is it had set for about 2weeks and the temp dipped pretty good and messed with it. I also have some corrosion on my batt cables just haven't had time to clean them so that could be part of my issue as well.
