Default 02 Sensor Codes

Just took the car for a ride, and I got 4 codes, all of them 02 sensors (Bank 1 Sensor 1, Bank 1 Sensor 2, Bank 2 Sensor 1, Bank 2 Sensor 2 IIRC). I'm !cats, so I thought I didn't have any 02 sensors? Is fixing it just pulling out the old 02 sensors, and popping in the new ones?

Thanks,
Chris

the front sensors bank1 senso 1, and bank 2 sensor 1 are REQUIRED for the engine to monitor a/f ratio.

without that you're engine is flying blind and will run like crap.

the rear o2 sensors are just there to monitor the cats, and if removed will throw a code, but will have no affect on the running condition of the car.

Thanks alot. The car was tuned after the removal of the cats, so there was no code up until yesterday. So because the front 02 sensors may have went, would the code just pop up for the back two as well?

The car ran normally after the code came up as well.
