says its a turbocharger boost control position sensor circuit range/performance. my check engine light came on and this is the code it gave. Im new to this and can anyone help with what this is, how hard to fix and cost of part. Im used to working on gas engines but this is my first diesel.

any help would be greatly appreciated.

 

Has recall J35 been performed? I know this update had to deal with alot of soot issues they were having.
