Who knows 5.7 fault code diagnostics?

So as Frank just stated its only 105k miles as I stated the odometer in kms as I'm in Canada , FYI, this motor ate a camshaft at 125kms because of the whole vvt thing and all the solenoids were replaced then, it was done at the dealer, a big job to the tune of 5k! I'm leaning towards it being a bad chain or tensioner but think I'll tackle myself.
