What does P0442 code mean when the check engine light comes on?
The code means the computer has tried to vent the gas tank and has found a small leak in the vent system.
You may need to research the code to get the testing procedure for your model and year.
Hope this will work, I will research to find the testing procedure, thanks

A P0442 code means Evaporative Emission Control System Small Leak Detected. This means there is a fuel vapor leak in the EVAP control system. It also means it is a very small leak. The leak could be as tiny as 0.04 inches in diameter. A loose or cracked gas cap can cause this code. Even an aftermarket gas cap, one that is not from the car's manufacturer can cause a P0442 code. It can also be from a small leak or hole in a fuel vapor hose, tube or O-ring. Try removing and replacing the gas cap. If you are mechanically inclined, try inspecting the hoses, tubes, and O-rings. You may also want to take your car to an auto repair shop.

This one is simple
1. Remove dip stick and filler cap.
2. Remove oil plug from oil pan and drain oil into an appropriate pan.
3. Remove and replace oil filter. (Filter will drain oil, just be aware to try and get it into the pan.
4. Refill oil. Start with 3.5 quarts, put cap and dip stick back on and start car, wait about 10 seconds and then turn off.
5. Check your dipstick for proper oil level.
And thats it you are done.

P2626 O2 Sensor Pumping Current Trim Circuit/Open (Bank 1 Sensor 1)
I'll sure this has to do with a faulty O2 sensor. This sensor is usually
located around the header of your car, or down more on your exhaust.
Try disconnecting your battery for 30 mins, hook it back up, and start
your car again. This will erase the error. See if it comes in again.
Hope this help (remember rated this post).

"Fuel system too lean at idle". It's an air/fuel ratio that is not correct, possibly a vacuum leak somewhere. Or a leaky exhaust pipe. Could be related to intake manifold gasket. Somewhere, air is getting into the engine.
I suggest taking it back to the dealer under warranty. I think Hyundai is 10yr./100k for the original owner. 5yr./50k if not. Ask first if covered, and ask why not id not covered.
