Code P2006 2011 Hyundai Tuscon

CBD II codes: P0302, P0170, and P2006 Can the engine problems be resolved by using a fuel additive/cleaner and replacing the fuel filter?

I would have to say NO. You may review the code information and see it is going to take a bit more than a filter and fuel change.
