what will happen if i dont plug it ?




If you don't have mileliminators and you do not put the lower O2 sensors in,

P0136 Downstream Heated Oxygen Sensor circuit fault - Bank No. 1.

P0156 Downstream Heated Oxygen Sensor circuit fault - Bank No. 2.

If you have mileliminators, you need to plug the connectors in and then find places to attach the O2 sensors.
