P1226 on a Kia indicates that the engine control module (ECM) has detected a low-voltage condition on the control circuit for fuel injector number 2. This means the ECM's command signal to that injector is seeing less voltage than expected, which can prevent the injector from opening properly and cause a misfire or rough running.
