Do you know which sensor is bad? Have you had the computer scanned? most of them just unplug from the wiring harness and you unscrew the sensor out of the exhaust pipe either before or after the catalytic converter. If they are bad you can generally shake them and you will hear them rattle due to the porcelin breaking.
