There was a GM service bulletin on this issue, but not for the year of your truck. It's possible the problem has carried over to the following production years. Check this link for a write up and a link to the bulletin: http://engine-codes.com/p0521_chevrolet.html

I bought a used 2012 Chevy 1500 two months ago with the same problem and code. The sensor has difficulty reading the gauge but is not a major issue. Replaced sensor and problem goes away. It's a computer issue that isn't major
