Hello,

The code:
P1130 - A/F (air / fuel ratio) sensor circuit range / performance malfunction (bank 1 sensor 1).

The A/F sensor or the air / fuel ratio sensor is the oxygen sensor that is located before the catalytic converter on this vehicle.

This code can be due to a bad oxygen sensor or faulty harness for the sensor.
