My car is wayyyyyyyyy over due on it's inspection because of the O2 sensor I believe. I ran over a semi truck tire going down the interstate one night and it ripped up the bottom of my car pretty good. It ripped what I believe is the O2 sensor to shreds. It has a blue connector and the wires on one side are blue and white and on the other side they are like red, green and some other colors, but I can't tell because it is a little dirty underneath my car and it's hard to tell. I know it's hard to understand, but if you know what i'm talking about, is this the O2 sensor and could you tell me what wires go together so I can just fix it myself.
