Your error code indicates the air fuel ratio is wrong. Only three factors affect A/F ratio, MAF sensor, upstream O2 sensor such as B1S1, and potential air leakage after MAF. Therefore I said first check MAF and O2 sensor. If O2 sensor stable at 0.75 v and not change quickly with time, that indicates a bad sensor.
