My check engine light came on and I took it to Advance Auto and it read the code "PO 136" O2 Sensor circuit malfunction (bank 1 sensor 2). Did anybody know where that is located and how I would go about replacing it? I know it is a lot cheaper to do it myself, I'm just not familar with where to find it and how to start. Any help would be greatly appreciated.
