Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

If the cam sensor fault is still showing up as well as a faulty mass air flow sensor I would replace the cam sensor and then have the cam and mass air flow sensor wiring as well as all other wiring checked for any issues on the engine needing corrected.I have seen damaged and corroded wiring that can cause a fault like this here needing repaired.
