It means you may've* gotten real lucky. The camshaft position sensor is a relatively easy changeout on the 2.4L I4 motor. It's at the rear of the engine (driver side). Accessing it will require removing the cam cover (aka valve cover). Go to
HMAService, register (free), and access the online service manual for your year and model Sonata I4 motor for instructions. Note, though, that in the upper engine teardown, what the book lists as the
crankshaft position sensor off the exhaust camshaft is really the camshaft position sensor. I went round and round with that one until I looked up the schematic diagram in the emissions control system for the I4 and it properly identified the camshaft position sensor off the camshaft and the crankshaft position sensor off the crankshaft as a person of even minimal intelligence would've logically assumed in the first place. If you're uncomfortable delving into this type work, any competent mechanic should be able to handle it in less than an hour. Other than expendable shop materials, the parts list probably won't consist of anything other than a new camshaft position sensor and a new cam cover gasket.
*There is the possibility that the code only points you in the right direction and that your camshaft position sensor is healthy, but being blamed by the failure of some other electrically associated part. Camshaft position sensors are a known problem area in most cars, though - and your car is at about the right mileage. You're probably not looking at a major outlay.
Not to beat a dead horse, but are
you the original owner? Hyundai's explicit 10 yr/100,000 mile powertrain warranty states under
ENGINE:
Cylinder block/head and
all internal parts, manifolds, timing gears and belt, timing cover, gaskets, and seals, oil pump, water pump, fly-wheel, oil pan assembly, and rocker cover and engine mounts.
I realize there may be interpretation questions about "all internal parts", but it still may be worth a question to a dealership's service manager. Good luck
