Ok I need to know this once and for all how many o2 sensors does an '01 V6 Camaro have... Is it one in the front and one in the back (pre and post cat) or is it 2 in the front and one in the back? And what side are the front ones located (which side and rough location?) Please help me out because i'm rackin my brain about this...

Thanks in advance,
-Paul-

 

To the best of my knowledge, we have four.

I've only changed the sensors before and after the cat, but I believe there some on the manifolds.

 

Three total (one on each manifold, one after the cat)
