1999 Hyundai Sonata Engine Size unknown Front Wheel Drive Automatic 57000 miles

I am having Hyundai Sonata 1999 model GLS V6. Its engine check light is on. And It is showing code P1154. As I got information from one mechanic that the oxygen sensor (after front catalytic converter, left) part no. 39210-37180 is need to be replaced. Please suggest me how difficult is it to change. And what precautions should I take while changing this and is the only solution for solving this engine check light on. And Appx. Expenditure on this repair. Please provide me any picture where it is located and how it can be replaced.

Go to a auto parts store and ask them for a o2 sensor socket. Use the socket and simply unbolt it from the manifold. I dont have a picture but its the only thing on the manifolds and exhaust pipe that has electrical wires going to it

I have a 2001 sonata and the o2 sensor is between the motor and the firewall. Look down to the heat sheild on manifold at back side of motor, it will have a wire coming out off manifold to a plug. You need a small flat screw driver to release the clips connecting the plug and a socket that has a slot cut into it so it will fit over your connected sensor. Auto zone will loan you the tool. It is tight but I changed mine this week and I am no mechanic !
