any body can tell me about o2 sensors trouble code by scan tools ?
i know there is 2 of o2 sensors in the both of catalytic is that right ?

There are a whole bunch of O2 sensor codes. O2 sensors have a heating element, so if that's not working you can get a heater code (probably the H02 code). On the GTO, you have four 02 sensors. Two main ones in each bank before the cats and two post cats sensors. The front sensors are the most important, the rear sensors just signal you when the cats stop working.
