P0138 HO2S Circuit High Voltage Bank 1 Sensor 2
P0140 HO2S Circuit Insufficient Activity Bank 1 Sensor 2
Pulled both those the other day - I assume it is o2 - but which one? I have been having a few, small, minor issues with the ACR since rebuild, but I had this one time before. Does this mean one of the sensors is going kaput? I still have all my power like before... just wondering which sensor it is... upper or lower?
Codes - is this another code for o2 sensor?

Sensor 2 should be the downstream. Might have died, since the PCM "sees" it not changing value. Or a wire is shorted.
