DTC P0230-00: Fuel Pump Primary Circuit: General Description
WARNING: This page is about a different car, the 2024 Kia Sorento. However, it is still accessible from the selected car via links, so may be relevant.
The ECM pump relay is powered by the Main Relay when the ignition is in the "ON" position, the ECM grounds the "control" side of the fuel pump relay. When the ignition switch is turned "ON", the ECM energizes the fuel pump relay closing the "load" contacts and sends power to the fuel pump. The ECM monitors the control circuit between the fuel pump relay and the ECM.
