Code P2247 KIA Description

The P2247 code for KIA indicates a problem with the O2 sensor reference voltage circuit for Bank 2 Sensor 1. This sensor is responsible for measuring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel ratio for optimal combustion. When the reference voltage circuit is open, it means that there is a break or interruption in the electrical connection, preventing the sensor from functioning properly. This can lead to inaccurate readings, causing the engine to run inefficiently, resulting in decreased fuel economy, increased emissions, and potential damage to the catalytic converter.
