Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Bank one - cylinders 1-3-5 - appear to be at the "back" of the engine compartment. "There's no downstream" - what does that mean? Each bank has a pre and post cat oxygen sensor. And, codes do not necessarily indicate component failure, but rather something in the related system that is not measuring properly -- so use caution before jumping to the conclusion that a component like a sensor must be changed.
