Answer 1

P1130 A / F Sensor circuit Range / Performance malfunction (Bank 1 Sensor 1)

P1150 A / F Sensor circuit Range / Performance Malfunction (Bank 2 Sensor 1)

Bank are the location of the cylinder , Bank 1 is where cylinder 1 is located and the other side becomes Bank 2. When it comes to Sensor , sensor 1 are the upstream 02 sensor or the engine management sensor , Sensor 2 are catalytic monitor sensor or the downstream 02 sensor.  If you have P1130 and P1150 replace the A /F (reffered to as 02 sensor) relay. Most shop when they replace any upstream 02 sensor recommend that the A/F heater relay be replaced.
