what that means is that the ecm(main computer) is not getting a voltage signal value from the o2 sensor. this could be due to a broken wire,bad plug or a bad sensor please rate this thanks

how many miles are on it? if you have over 70k the head bolts may have let loose and allowed the head gaskets to leak they all do it
