Hi .
If the check engine light comes on then you could have any of 100s of problems does not mean the O2 sensors are bad ,you need to have a scan tool hooked up and check for malfunction codes .
If you have the 4 cylinder you will have 2 sensor one pre cat and one post cat .
The V6 engine you will have 4 sensors 2 pre cat and 2 post cat
with 2 on each cylinder bank .
One cat per cylinder bank .
Cat = catalytic converter..

Re: Hyundai Sonata; having had one lombada replaced the orange light still glows; I've been told that having one new part has caused the other to mulfunction. Could this be the case?

Would help me a lot if i had the first malfunction code when the first sensor was changed and now the new malfunction code that you have .If the code is the same or if the code has changed .In most cases when one has a O2 sensor ( lombada ) code its does not always mean the sensor is bad but could be a bad wiring harness or a bad ECM . Now you need to ask what the first malfunction code was, and which sensor they replaced. Now after replacing the sensor what is the new code . You will have to let them know that you know what is happening here. don't let them take advantage of you Say . "can you please tell me what the first malfunction code was from the first diagnostic test .And now what is the new code .\Get me this info and i can help you. Which engine do you have the 4 cylinder ,
