That's a pretty RELIABLE code!... You have a bad CAT (Catalytic Converter). Trust it to be accurate. The conditions which set this code is when the Upstream O2 sensor's data/signal is compared to the Downstream sensor's data/signal... when they are nearly identical, that's when this code is set (unless you have an exhaust leak).. If there is an exhaust leak.. repair it, then retest/recheck.

The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the exhaust camshaft. There is no variation in valve timing of the exhaust cam because the exhaust camshaft is driven by the timing belt. The timing of the intake cam is varied by the relative operation the CVVT vane to the housing. This system helps the engine decrease exhaust gases and increase engine power and fuel economy by changing the valve open/close timing of the intake camshaft. The deviation of the camshaft position from the target point is evaluated during stable driving condition. The PCM accumulates this deviation for a certain period and sets DTC P0010 when the accumulated deviation is too high. The target camshaft position is a predetermineded value depending on engine speed and throttle angle communicated to the PCM. The MOST FREQUENT CAUSE is DIRTY OIL. The NEXT most frequent cause is restriction/obstruction of OIL FLOW to the CVVT unit (oil control valve supplies this). Remove this valve & inspect it for aluminium flashing (bits of metal which might be interferring with the valve's operation). We use Z-MAX treatment to solve this problem at our service center (after changing oil & filter (genuine Hyundai Oil Filter).

7 out of 10 times that means that one of the cat's have gone bad. Most of the time it happens when your mileage is around 100,000 miles. The only thing is to do is to change the bad cat.

Have you checked for any small vacuum leaks on any of the emissions hoses? A vacuum leak causes a "too lean" reading. If no leaks, you could have a malfunctioning emissions valve, bad oxygen sensor or fuel injection problem. First I would remove the spark plugs to see if they verify that you have a lean condition. Lean plugs will look white. Google for an image of what a lean burning plug looks like if you like. If they look like burning lean then proceed to trouble shoot each possible area. For example if only one plug shows lean but the others don't you know to look at the injector for only that one cylinder. So don't mix up which plug came from which cylinder.

A code P0430 may mean that one or more of the following has happened:
First, inspect for exhaust leaks.
Next step is to measure the voltage at the oxygen sensor on Bank 2. In fact, it would be a good idea to test each oxygen sensor while you're at it.
