Bank one is near the firewall, B1/S1is located in the exhaust manifold near the firewall, bank two is near the radiator, the sensors in the manifolds are A/F ratio sensors, the sensors behind the cat converters are designated as #2 sensors and are O2 sensors. There is only one O2 sensor behind the cat on this model.
