Thanks,

Sensor one is a front sensor i think

Bank one sensor one is the front O2 sensor on the right side of the engine, these things usually last about 60000 to 70000 miles, change it quick because it will affect your a/f ratio!!!!! on second thought, might as well do both sensors at the same time because the other one is probably right behind it(the front sensor on the other side).
