jannster13 Posted August 7, 2008 Share Posted August 7, 2008 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. Quote Link to comment Share on other sites More sharing options...
