For this issue, should be the same across the board, but really need to tell us what you have first.

bank 1, sensor two would be the rear sensor on the passenger side.

Its a infiniti g35 coupe 2005...i all ready change the sensors but it still marking "low" circuit

You'll need to get under the car with a digital multimeter and confirm electrical voltages per the FSM. This could be a wiring issue and not a sensor issue

Did you ever figure out the problem? my car is doing the same thing
