Code P0265 KIA Description

The P0265 diagnostic trouble code (DTC) for KIA vehicles specifically indicates an issue with the Cylinder 2 Injector Circuit being too high. This means that the fuel injector for the second cylinder is sending a higher voltage signal than what is expected by the Engine Control Module (ECM). The fuel injector is responsible for delivering the precise amount of fuel into the combustion chamber at the right time. When the injector circuit is reading high, it can lead to an imbalance in the air-fuel mixture, causing poor engine performance, reduced fuel efficiency, and potential damage to the engine over time.
