O2 sensor location

[quote="Mikeybdman"][quote="deckj"]hi I am going to replace an o2 sensor on my 96 grand am gt. I have heard it is on the exhaust pipe in front of and in back of the cat converter. I only see the sensor behind the converter and it is the one before that I need to replace. If you can tell me where it is it would be very helpful. Is it on the manifold?[/Quote]

which engine do you have?[/Quote]

On a V6 model the HO2S1 is located in the rear exhaust manifold. Right before it connects to the exhaust pipe. The HO2S2 is located behind the cat converter.[/Quote]
