Looks like your engine is outside the balance shaft issue. From your VIN the Engine number is: 273961 30 177576

Pull the solenoids to check if aligned properly behind solenoids. Although hard to look straight and see the timing mark, it may not be exactly straight on.

 

Thank for reply’s removed belt and idler pulley. Cleaned and marked timing cover, 305*, and 40* in case I need to remove front covers and check gear marks. All marks look centered. I swapped right bank exhaust position sensor with one from Left bank. Code actually stayed off for a little while then returned.

 

Did end up pulling specific codes instead of just the generic p0017. Replaced timing chain guide gear and right bank VVT exhaust sprocket. Although not in affected range there was quite a noticeable difference. In side by side comparison of new and old chain guide gear. After resetting camshaft adaptations with autel ms906 and driving. Codes have not returned.

I read something on another site something about if the cam sensors were leaking oil the oil gets in the harness and throw codes not sure where I read it or what the solution was but I just remember seeing something about that. Check your plugs for oil soaking.
