P0230 on Mitsubishi
Fuel Pump Primary Circuit Malfunction
P0230 on Mitsubishi vehicles indicates fuel pump primary circuit malfunction. Au7o has documented this code across 1 Mitsubishi model — most commonly on Eclipse. 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. Typical repair costs on Mitsubishi range from $75 to $400, depending on the specific model and root cause.
Common Causes of P0230
- •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)

Mitsubishi Eclipse(1 issue)
- 2G Fuel Pump Wiring Voltage Drop and Fuel Pump/MFI Relay Failure1995-1999
On 1995-1999 cars the fuel pump's factory wiring is undersized and its chassis ground (at the floor crossmember under the driver's seat) corrodes with age, dropping voltage at the pump into the 10-11V range under load. The paired fuel pump/MFI relay behind the center console can also fail. The result is intermittent cranking no-starts (no pump prime), stalling, and lean stumble or fuel cut at wide-open throttle on turbo cars — a problem so common the community-standard fix is the documented 'fuel pump rewire.'

What does P0230 mean on Mitsubishi?▼
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 Mitsubishi specifically, this code is documented across 1 model.
What causes P0230 on Mitsubishi vehicles?▼
