Is this the upper or lower set and is it the front or back sensor
SOURCE: O2 sensor wiring diagram for 2004 hyundai sonata
there is two wires then suposed to be same color they are not what you looking for but if you have a grey and a black wires it willl be one of those i hope and this help

Your question was truncated. I see that the bad sensor is on bank 1, but I can not see if it is the upstream (sensor 1) or downstream (sensor 2) sensor. The upstream sensors are mounted in the exhaust manifolds (look sort of like spark plugs) and have wires going to them.
You will need a 7/8" or 22mm wrench to remove the sensor (after disconnecting the wires). If your car has over 70,000 miles I STRONGLY suggest that you replace BOTH upstream sensors. One in each exhaust manifold.

there is a fuse for the o2 heaters if one of the sensors blew the fuse they will all be out

O2 sensors are tricky. sometimes like anything else they fail. many times though the exhaust mixture they encounter is out of their range and that shows up as a failure.since you seem to have no other problems , I would go ahead and change them, but don't be disappointed if the code shows up again (at least you know it's not the sensors.) I don't like using the process of elimination when doing repairs but sometimes you must.

No that is your oxygen sensor (O2 sensor) it's is placed on your exhaust system after the Catalytic converter. If you have a hoist to get under the car, you can replace the O2 sensor your self. If not you can buy the O2 sensor at Auto Zone or any other parts store like Parts Source and have a muffler shop install it for around $65.00 if not less since it's going to take about 15 min to replace. Good luck and hope this helps. You can take it to the dealer but that's going cost much more then the muffler shop.
