My truck, 2014 sport cc w/5.7, threw this code this morning. I drove to the gym and after I left it was still on. Got home and called the dealership to get it fixed under warranty and they told me to bring it up. Of course, when I got in the truck to take it the light was off. When I got there they told me there was nothing they could do with the light off. He told me it could be that it was too cold this morning. It was 55° when I went to the gym and it was the warmest morning all week. Does that make sense to anyone?

No it doesn’t make sense. There is a PCM software update for that code. If the update doesn’t apply or doesn’t fix it, then chances are it needs a new bypass valve. They could have at least ran the bypass valve test with the scan tool.
