Where is bank 1 O2 sensor?
Where on the vehicle is the bank 1 O2 sensor? I had thought it would be on the exhaust mani, but a picture in google images seemed to indicate otherwise. I would appreciate any help/links. Thanks

What problem are you having?
"Bank" refers to a bank of cylinders, not the oxygen sensors themselves. Since the Fit uses an inline engine, there is only one bank of cylinders, referred to as "bank 1." For the '07-08 Fit, there are two oxygen sensors for bank 1: a primary oxygen sensor (a.k.a. air/fuel ratio sensor) and a secondary oxygen sensor, which monitors catalytic converter performance. The primary sensor is screwed into the exhaust manifold downstream of the 4-1 collector. The secondary sensor is screwed into the converter.
