Galant 2002 V6: DTC p0141 - Oxygen Sensor - Heater circuit malfunction

I have replaced the bad sensor with a new Bosch Oxygen censor part number 13412 and cleared the P0141 code using a scan tool. However, I still get the
P0141 after the car started. I checked the wiring harness and connectors and it looked good. I don't know what else do I need to check or do to correct this problem. Anyone have any ideas what's wrong ?
