There may be a loose or dirty connection at the sensor terminal , clean or tighten if ok trace the cable back to any join pull apart and clean . You may have to clear the fault from memory by removing battery cables for a few minutes . Make sure you have the code to reset the wireless ect.
Reset the code may not return.

This is where at home diagnosis and in-shop diagnosis diverge. A shop will begin by checking that bank for an over rich or lean condition, then moving closer to finding the problem which for example could be an injector with a bad spray pattern or leak, or a minor vacuum leak somewhere .(too many other items to mention) You can do further testing with the use of a manual and a decent digital volt-ohm meter.It takes more time and isn't always as productive but most times with a bit of research and learning on your part the problem can be found. Unless I made a lucky guess, I could spend all day writing down ideas and would not be correct.

Did you use a aftermarket O2 sensor or a genuine Hyundai one? If it's an aftermarket one it may be bad or not as good as the OEM one. See here for more details and other potential causes: P0133

Try first to clean out the MAF sensors and the intake with tuner cleaner spray. Check also the the fuel regulator. Check also for holes and gapes from the air filter to the intake manifold. An error on the O2 sensor mean does not mean it is faulty. It may also be related to the air fuel mixture. Check also the wiring of the sensors (MAF and O2).

I had the same problem it was a vacuum leak the leak was coming from a hose that is connected to the valve cover and the back of the engine all I did was replace the hose and there is no more codes
