Troubleshooting with Precision Diagnosing O2 Sensor Bank 1 Sensor 2

I have a 2003 Element with a ODB code: P0141 I believe this calls for Replacing the O2 sensor for bank 1 sensor 2. My question is which of the two 02 sensors ... So all of the oxygen sensors will be bank 1. The oxygen sensor or Air/Fuel sensor closest to the engine in the exhaust manifold will always be Sensor 1. The O2 ... So, it's the downstream sensor on the rear. You'll have to access it from underneath the vehicle. Sensor 1 is up on top. That said, the code you ... Bank 1 Sensor Upstream Oxygen Sensor Replacement for Audi A4,A4 Quattro,A5,A5 Quattro,A6,A6 Quattro,A8,A8 Quattro,Q5,Q7 R8 S6 S8 2L 6L,Replaces#234-5019 ... Bank 1 is the passenger side, Bank 2 is the driver side, Sensor 1 is it he highest in elevation (the upstream sensor), Sensor 2 is the lower in elevation (the ... Bank 1 sensor 2 is located downstream, usually behind the catalytic converter. Regardless of the bank, all oxygen sensors use the same naming pattern. The O2 sensor bank 1 sensor 2 is located on the same side as cylinder 1 in your engine, but it's positioned downstream of the catalytic ... “Sensor 2” indicates the downstream oxygen sensor after the catalytic converter. In a typical exhaust system with one catalytic converter, ... two are directly below the intake/exhaust manifolds, and the third is at the skid, by the transmission. there are four oxygen sensors...two ...
