I have a code of p1130 air fuel sensor. where is this located.

Here's a video. It depends on what bank the code reader says it's on. You may have at least 3 on your car. Maybe two. Notice in the video what bank he says it's located on. It's just an oxygen sensor. Will be located on your exhaust manifolds and exhaust pipe. https://www.youtube.com/watch?v=dfAB9jQ67KM

You should have 4. Here's a diagram.
