What does code P0017 for a check engine light on a 2013 Hyundai Sonata. What pets would that normally point to as possibly defective

Thanks. It indicates correlationbank 1 sensor B. Which location would that be if left or right side and the front or rear position? This is driving me crazy. Light stays on now. N e info is most appreciated! Im a disabled female veteran and u know how that goes. They see us coming

Firat thing to do is change your oil.....having dirty oil in hyundai and kia's will trigger this code. If that doesnt change anything then buy a cam sensor....there is 2 of them (being double overhead cam) but you can try one....then try other if first one doesnt solve it....next step is crank sensor (a bit of struggle to change but doable)...after all that is done and problem still there....you def. Have issues with timing components (such as guides being warn out/broken...cam pulley etc.) im not a professional nechanic....but had same issues and in my case was oil change + crank sensor. Hope this info helps. Good luck!
