What are chances all my 02 sensors are bad?
Car is running fine. Getting usual gas mileage. Have reset all codes past week and still getting 02 faults pretty much all 4 I believe. Here is screen shot of today. I’ll ad more. I plan to bench check them soon.

Not much chance if out of the blue.
FYI,
It's a good idea to check your codes in the Rave Workshop manual for LR's description.
Doesn't appear your four codes indicate four bad sensors.

sensor 1)
Front sensor LH bank open circuit
P0135 O2 sensor heater circuit malfunction (bank 1,
sensor 1)
Front sensor heater LH bank - short/open circuit
P0150 O2 sensor circuit malfunction (bank 2, sensor 1) Front sensor RH bank stoichiometric ratio outside

Best before doing any O2 replacement is to clean the MAF first with MAF cleaner. Saturate it until it drips and let it completely dry. Might be dirty and sending all odd signals to both your O2 sensors.

And be sure to only clean the MAF when cold. Don't hook it back up or start the truck until it is completely dry.
