My truck is throwing 2 codes. P0060 HO2S Heater Resistance
(Bank 2, Sensor 2) and P2272 o2 Sensor Signal Stuck Lean - Bank 2 Sensor 2. From what I read this is the downstream drivers side sensor. I have read online and have found conflicting answers. Is the oxygen sensor possibly bad or is there something else causing the code to throw? My truck is an 04 4.6 with 65k miles on it. I was told by the PO that is was maintained regularly. Any help is greatly appreciated!
