My check engine light came on yesterday while driving in town at about 40 mph. The truck is running fine. The dealer can't get it in until Wednesday so I stopped at a parts store and they read the codes, 340 and 344. Both are problems with the camshaft position sensor. Has anyone else had this problem?

I haven't heard of this issue - if be interested to see too. What year is your truck ?

It's a 2012 with 18,000 miles. I had the CAC problem at about 14,000 and now this.
