Well to start with I would make sure that you replaced the correct sensor. The one after the convertor. Now that you are sure of the sensor you may need to trace those wires to make sure they are good and not damaged. If this was a universal sensor you replaced it may need the connector double checked to make sure the correct wires are connecting. If you could post back the codes it may be helpful.
