6 SES codes, could all the o2 sensors went wrong?

I had a problem like this once and after we removed the O2 sensor we found a small break in the plastic insulation around the sensor wires.

Jordo which sensors did you remove, post or pre cat?

Testing procedures for the O2 sensors is in the FSM. You should be able to get a good idea of what's going on by monitoring the sensors using an OBD/CAN scanner that allows you to do so. Not sure if what you are using will do that but, if you already have the OBD-to-USB i/f, you can find the software for free.

Edit: since all the sensors are throwing DTCs, I suspect a wiring problem or extremely careless mods.

That's where my money is. Something got messed up during the TP install.

Stupid question, but are the sensors in the correct locations?

I think so because only the post cats were disconnected. I have uprev and cypher but dont know which setting to read?

I also suspect it is an electrical problem. I might take it to the dealer for a deeper inspection

Post, and only one, but the heater circuit codes usually mean the sensors are toast.

Random thing for me -- but there was clearly exposed wire on the sensor. replaced the sensor, problem solved.

On a related note, do you have defoulers for your secondary O2's or have you tried the steel wool trick(or both). In the end, for me, having that SES code disabled with uprev was the only solution for post cat codes (other than the heater one that is)..
