I have purchased last year a F150 XLT crew cab 2WD. Found it to not be a completely good experience. Basically it does the job well of being a truck. So it’s not all bad.
I have question to the group. After I bought this truck I had to arrange to have the spark plugs replaced at 100k and also went ahead with new coil packs as well. One thing I didn’t see at first was the prior owner replaced one coil pack for cylinder 6. This was done prior to purchasing this truck. After a period of time it registered a MIL code P0430. And this code will appear and clear itself at random.
So I bought a OBD2 reader called BlueDriver over using my Autel. And what I see disturbs me. The indication is that my bank 2 cats are shot?? I think a random voltage readings from a rear sensor is not good. Please note sensor 2 bank 2 against the smooth voltage of sensor 2 bank 1.
I am using a product called “Cataclean” currently during these readings as recommended.
So are Bank 2 cats shot or what ghost should I chase and why?
Voltage reads of O2 sensors during driving.

Welcome to the forum !
Looks like bank 1 sensor 2 is not switching, check for power and ground at the connector for that O2 sensor.
Look at the harness closely to make sure it didn't melt on anything hot or rub through from coming unsecured.
I will look at this sensor closely. In fact all of them. Its amazing for miles on this truck to see the undercarriage so rust free and clean. So this check will be easy to do than normal. Will advise what I what I find.
