Hello,
I have my check engine light on, and getting terrible MPG. I get DTC codes P0059 and P2197. It states that the o2 sensor bank 2 sensor 1 is essentially "not working". Do I need to replace one or more O2 sensors? If so, which on on the 3.5L V6? Also, if so, wht is the Ford Motorcraft part number for the replacements?
I'm looking here for parts...
One last question, weird too. I purchased this vehicle used, and the OBDII port looked funny to me, not "SECURED" correctly. So I look behind it, and I look at the wires and there is a wire that has been cut, and an extension added to it (to make that wire longer). I took a closer look and a few other wires had a millimeter of shielding pulled back, but it was not immediately noticeable because electrical tape was used to cover these cuts in shielding. Could this port be doing something to the o2 sensors?
Thanks in advance....
