oxygen sensor replacement?

Thanks for the reply, however I am a little confused.
In one paragraph you say that bank #2 is the passenger side , then the next paragraph you say it is the drivers side. Could you please let me know what side it acctually is.

Many thanks
Lyle

Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).

sorry about that i was saying the passanger side had the #1 cylinder so the one oppositve of that is the drivers side.

your looking at the drivers side.
