Code P1182 MINI Description

The P1182 MINI code indicates a problem with the O2 sensor in Bank 1 Sensor 2 during coast down fuel cut-off. The O2 sensor plays a crucial role in monitoring the oxygen levels in the exhaust gases, providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. Bank 1 Sensor 2 is located downstream of the catalytic converter and is responsible for monitoring the efficiency of the catalytic converter.
