2002 Suburban 1500 5.3 Flex Fuel

So I am driving home last night and the service engine soon light came on. I just put gas in the car about 15 miles before the light came on. I did a little research on the sensor so far, and it looks like it could be water in the fuel from bad gas. Has anyone ever had this before. Also where is this sensor located?
Thanks in advance
