On ur dp.
Both of them...one before the cat (HO2S-1) and one after the cat (HO2S-2). they are both heated sensors to help the engine get into closed loop -- so the ECM can run off the sensors quicker...the 2nd one is used to analyse the cat's condition.
On the 05/06, the first sensor is in the exhaust manifold 07+ has both sensors on the DP correct me if i'm wrong
