Timing is to far advanced causing vehicle to run hotter than normal you'll need to take it to a dealer it can be a few items causing this ecu unit faulty sensors or oil valve hope this helps

Sometimes the mass air flow sensor will become clogged with some miniscule particles of dust or whatever else. When you open up your hood somewhere near where the air filter box is, there will be a hose running from that to the engine, the mass air flow sensor should be somewhere in near there. They are easy to remove and should be held in place with a few screws. Make sure not to touch any of the electrical connectors on the inside or allow them to get dirty. I used mass air flow sensor cleaner from the local parts place but it is a bit pricey. There may be some alternative cleaners available that are not as expensive. Take the sensor to a relatively dust free area and spray it all over with the cleaner and allow to dry. At the same time under the hood where the sensor was spray that area as well. Once the sensor has dried out re-install it and you should notice an improvement. If the problem still persists you may need to change your spark plugs, or spark plug wires.

Just disconnect your battery for a couple of minutes.

more than likely you have a bad oil control valve if in fact you have an 06 sonata. They are chain driven engines... You can ohm out the valve and get a good reading even when the valve is bad. Pull it out and check to see if it is clogged, if it is thats more likely your problem. If it is clean, go ahead and replace the valve. Hyundai calls them the oil control valve (OCV) and usually located on the head close the the variable valve sprocket.

Fuel trim too lean. Usually means vacuum leak. Look for crushed,broken or melted off vacuum hoses near intake manifold. Or an obvious hissing noise at a normal idle. If so replace or repair clear codes your done. If not obvious take carb cleaner spray with nozzle attached car running & go over all vacuum hoses,intake manifold,egr valve see if idle raises if so you found leak. Repair. Could also be bad oxygen sensor switching bad o2 sensor but rarely.
