Possible causes are:
Short To VPWR Or HO2S Circuit
Water In Connectors
Open In GND Or VPWR Circuit
Low Battery Voltage
Corroded Or Poorly Connected Terminals
Damaged HO2S Heater
Damaged Powertrain Control Module (PCM)
Faulty HO2S Heater
Inspect HO2S connectors for loose, damaged or corroded terminals
