Mine were blocked open by the PO, but when I bought the truck, it didn't have a tune. It wasn't until the tune and hard driving that it'd come up. I searched around in the trunk and verified it was plugged back there, yet I still got the warning on the daily, to the point where I could tell by how the engine sounded that it was coming. Once I deleted that extra T in the engine bay, my problems finally went away.
