Frequently asked questions
What does P0230 mean on a Genesis?
P0230 stands for "Fuel Pump Primary Circuit Malfunction." P0230 means the engine computer detected a fault in the fuel pump primary circuit — the control side that switches the fuel pump (or its relay) on and off. The PCM energizes this circuit to run the electric fuel pump that delivers fuel to the engine; if it sees voltage that is too high, too low, or out of expected range, it sets this code. Because the pump may not run correctly, the engine can crank without starting, stall, lose power, or hesitate. This is a circuit/control fault rather than a direct measurement of fuel pressure. On Genesis it is documented across 1 model: GV80.
What are the most common causes of P0230?
The most common causes of P0230 are: Faulty fuel pump relay, Damaged wiring or connectors in the fuel pump control circuit, Corroded or loose ground/power connection, Failed fuel pump or fuel pump driver module, Blown fuse or fusible link, Open or short in the primary control wiring, Faulty PCM driver output (rare). The specific cause varies by vehicle.
