oxygen sensor problem
I drive a 99 explorer sport, my engine light came so I took an autozone to have them scan it, it came up that my bank 1 sensor 1 oxygen sensor was bad so I replaced it. Then engine light stayed on so I took back to autozone to see what codes came on. Same problem the bank1 sensor 1 was still bad. s I changed it again thinking maybe the sensor I just bought was bad but that did not work either. I was wondering if anyone would have any idea where to go from here. Someone told me that it could be a blown fuse but I did not know that the o2 sensor had a fuse, any help would be great!!!!
