If you have a grand prix there are 2 o2 sensors. One before one after. The one after the cat is absolutely useless and most people bypass it. The one before is vital.

Thanks Dsmuts and Frosty,
I have a 2001 Grand Prix. 3.1 V-6. I can not remember the code number off hand. I am going use the code reader on it again tomorrow some time to get the code once more and make sure nothing new has popped up. I don't think I can bypass the downstream O2 as I live in NYC and have to get an inspection before registering the vehicle. I am pretty sure I need to make sure my CAT and the sensors are working. Thanks for the info though. I saw a diagram of the exhaust that showed 4 sensors. as i said above 3 in bank 1and 1 in bank2. I appreciate the input... I won't go crazy looking for the other two.
