    P0153 issue won't clear code

    Having an issue with my 07 wrangler 3.8L, can't get rid of P0153 code. I have put in a renewed ECM, new cats and O2 sensor,new exhaust manifolds. After clearing DTC P0153 code comes back as soon as System says O2 ready. Any one else have the same problem, and how did it get resolved?
