TECHNICAL SERVICE BULLETIN: VOLUNTARY EMISSIONS SERVICE CAMPAIGN: EGR VALVE ASSEMBLY REPLACEMENT (SC320) - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to replace the Exhaust Gas Recirculation (EGR) Valve Assembly on certain 2024MY Kia vehicles listed in the table below. Kia has become aware that the EGR Valve Assembly in the subject vehicles may not have been manufactured to Kia’s specifications. This condition may cause the vehicle to release air pollutants which exceed Federal and California standards. As a result, the subject vehicles may exhibit an illumination of Malfunction Indicator Lamp (MIL) with DTC(s) P040500, P064200 and/or P065200.

The exhaust gas recirculation (EGR) valve assembly in certain vehicles (listed below) may contain a sensor that was contaminated with solder flux during manufacturing, which could potentially result in an electrical short. An electrical short within the EGR valve could lead to a Malfunction Indicator lamp (MIL) illumination (P0405, P0642, P0652, P0404/P049D/P240F). Follow the information in this bulletin to replace the EGR valve assembly and gasket.
