I need some help with this my 2011 has been sitting in the shop more than its been on the road, since the day I got it I have gotten this code daily. Over the last few months I have put in a fass lift pump, aftermarket cp3, new injectors, dealer gave me a new pressure releif valve, also clutch head bolts and other unrelated stuff.
So when I'm driving everyday when I hit operating temp it throws the code. If I shut down for 10 min and clear the code I won't see it again unless the truck sits over 3 hours and cools all the way down. Also it doesn't matter what setting my h&s is on it throws the code at the exact same time weather stock or wild.
Any ideas what this could be ?
