o2 sensor location

[quote:47446d34a0="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:47446d34a0]

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.

Nope. Should be the only sensor with wires going to it in the exhaust manifold.
