2010 LR4 went into restricted performance and gave code P0019- Camshaft position, bank B error. What are possible causes of this? I'm hoping this isn't a timing chain issue. No loss of coolant or oil.

More than likely a timing chain issue. The chain stretches and the tensioners collapse, allowing cams to jump time. You can pull the oil fill cap off and take a look at the chain. We use a long hook to tug on the chain. If its loose and sloppy, then you have your answer.

 

To close out this thread with a definitive answer, it was a timing issue, but not one of the usual failure points (from what I read here). The tensioner had become loose, changing its point of engagement on the guide, causing it to jump time. Went ahead and had my indy shop do the full service of changing all guides, chains and tensioners as at that point with the labor the parts are hardly the big expense.
