Code P1130 Buick Description
The P1130 Buick code indicates an issue with the HO2S (Heated Oxygen Sensor) circuit on Bank 1 Sensor 1. This sensor is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the HO2S circuit shows low variance, it means that the sensor is not responding as expected, leading to potential performance issues in the vehicle.
