P013a and P013c help!
2007 Grand Cherokee Overland
Previous owner had after market CATs installed. Started getting P013a and P013c codes and check engine light. Had all 02 sensors replaced, did not fix problem. Chose to have system totally replaced with standard OEM parts. 6 miles later check engine came on and same codes being thrown.
Mechanic says have to do a drive cycle to get codes to refresh? Is this true or fact that code came back after a few mile mean issue still not fixed?
