Recieved a PO153 Code a couple of days ago which is Bank two Sensor one slow response O2 sensor. I believe that is the front passenger O2 sensor. The question is I have replaced that sensor 3 wks. ago after it thru the same code 3 wks. ago. I'm sure the sensor did not go bad in just 2 wks, so I'm speculating a bad O2 wire extension. Could that be the case? I have long tubes so thats why I have the Extensions in case anyone wondered.
