The O2 sensors will report their voltage through the scanner, but if you run OL, their output is not used.

Your O2 voltages barely vary - only between .443 and .451 volts. I don't even know how that is possible, assuming they are connected and in the exhaust.

I would say no, your O2 sensors are not working.
Even tiny changes in the AFR will cause huge changes in the narrow band sensors; mine are constantly swinging from e.g. 100mv to 800mv.

They might be open circuit.

It helps (at least me) if you post your scanner's .cfg file too so that we are looking at the same PIDs.

Again your O2 sensors stay at almost exactly 447mV, indicating they are not connected correctly.

the code are PO134,, PO154 i have been reading about these, and most say change the sensor, mine are new i put them in when i did the motor swap , reasoning being the old sensors were different plug , i had to go to square plug to match wiring harness , could that be something in common ??? the motor is from a 06 truck and PCM is from 02 camaro i say the harness id for the 06 truck .. what do i need to do ?

thanks

A 06 truck is DBW. are you running DBW? The O2's are wired different on a truck vs camaro harness. You can repin the wires for the O2 sensors to make it work or change the tune to a truck tune and they will work if thats your issue. You're going to need to get a camaro schematic and a truck schematic and see what harness you have first.
