Edge Experts, 
  
I have good luck with the 2008 Edge w/ 70k miles until recently.  Getting the Check Engine Light and DTCs for a valve and cam timing issues on bank 2 (P0018, P0021, and P0022). 
  
* Fist off, which side of the engine is Bank 2? 
* Should I go ahead and replace the Camshaft Position Sensor, Valve Timing Solenoid, or other external sensors to attempt an easy fix? 
  
I read a couple of the older threads about new vehicles getting an engine teardown and expensive repairs so looking for your advice.
