Bank one is on the side of the engine where the number one cylinder is. Sensor one is the upstream oxygen sensor which is before the catalytic converter. Usually it's in the exhaust manifold or possibly in the exhaust pipe just after the exhaust manifold but before the catalytic converter. Hope that helps! Jim
