Where is bank 1 oxygen sensor on 2002 chevy tracker?
In a V6 bank one refers to the passenger side of the engine (locaiton of cylinder #1). Bank two refers to the drivers side (location of cylinder #2). There are two sensors per side. All are located in the exhaust manifolds. Both manifolds have a sensor just below where the exhaust ports collect and one at the end of the manifold right after a small catalic converter. The top sensors can be accessed from the top the bottom ones from below the vehicle. All are pretty easy to get to.
