P0230: Fuel Pump Primary Circuit Malfunction

Most Reported On
P0230 is an OBD-II diagnostic trouble code meaning “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. This code is most commonly reported on 2018-2020 Lexus IS (IS300, IS350), 2018-2021 Honda Accord, and 2018-2022 Honda CR-V, plus 63 other vehicles, with repair costs ranging from $50 to $2,000.
