Code P0175 KIA Description

When the diagnostic trouble code P0175 appears on a Kia vehicle, it indicates that the engine control module (ECM) has detected a rich air-fuel mixture on Bank 2 of the engine. Bank 2 refers to the side of the engine that does not contain the number one cylinder. A rich air-fuel mixture means that there is an excess of fuel in relation to the amount of air entering the combustion chamber. This can lead to poor engine performance, reduced fuel efficiency, increased emissions, and potential damage to the catalytic converter.
