Theres no such thing. It must have been sensor one bank one and sensor one bank two.
Thats means the front sensors are reading lean.

You need to get a wideband done to check your air fuel ratio. But it sounds like the codes were a lean condition detected by the PCM based a number of conditions. The codes were probably P0171 and P0174.

Take a look at your exhaust manifold, there is no way it can sense cylinder 1 being lean, they all merge together before the gasses hit the O2 sensor.
and how would it detect cylinder 1 lean in bank 2 when cylinder 1 is on the opposite side?
