suggest first replacing oil pressure sending unit I am presuming it it not low on oil.

oil pressure sensor is shorted out needs replaced..

Only a trusted local auto service shop or dealer can answer this for you because your vehicle would have to be up on a lift to actually see what's leaking in order to properly diagnose and repair. It may be as simple as changing the oil pan gasket or a cracked oil pan that would have to be either replaced or repaired depending on the size of the crack. There is also the remote chance that its actually something else that's leaking. Hope this helps.

Could be oil pooling in the valve cover caused by a partial blockage of the drain gallery, but you'd almost certainly get a oil low message too. I assume the oil and filter is changed regularly? You could try adding Marvel Mystery Oil, about 12oz for about a hundred miles and then change the oil and filter. Depending on your level of adventurism, you could drain the oil and replace it with new oil, except add a quart of automatic transmission fluid in place of one quart of oil. Some people say ATF is bad for seals, some people use ATF to rejuvenate leaking seals. I don't know who to believe. Run that for 100 miles and change the oil and filter. I've even seen someone replace their oil with kerosene and a quart of oil and run it at idle for 5 minutes, then change the oil and filter. Instantly freed 2 stuck lifters and the engine was fine.

Best bet would be to run the Marvel Mystery Oil first. Then, if the problem persists, either change the pressure sensor and see where that gets you or go for the ATF in the oil trick.

that should be it one easy way to check is unplug it and turn start the car and see if the light stays on.

Make sure your dipstick is wiped clean...then check oil again..if it still. is fine get your oil light checked...may be a short there.

It is the APP sensors , Your vehicle has electronic throttle control . P2122 Throttle Pedal Position Sensor Switch Circuit Low Your best bet would be to take it to a qualified repair shop .

Thanks.

Yes, the oil change schedual is a good thing to go by, but it is a recommendation. Have you noticed any leaks on the ground that you park on lately? You may be loosing oil and not know about it. There may also be a problem with your oil pressure sensor. It may need to be fixed or replaced, but don't worry. Your car is fairly new so it should be under warrenty if this is the case. I hope this helps! Please rate 4 thumbs up!
