P0230 on Alfa Romeo
Fuel Pump Primary Circuit Malfunction
P0230 on Alfa Romeo vehicles indicates fuel pump primary circuit malfunction. Au7o has documented this code across 2 Alfa Romeo models — most commonly on Giulia, Stelvio. 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 Alfa Romeo range from $200 to $2,000, 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)
P0230 on Alfa Romeo by Model
Alfa Romeo Giulia(1 issue)
- Low-Pressure Fuel Pump Failure Causing Stall (Recall 25V-586)2017-2026
2017+ Giulias can experience sudden engine stall or no-start due to a defective low-pressure fuel pump inside the fuel delivery module. The pump's internal commutator wears prematurely and loses contact, cutting fuel supply at any speed. NHTSA recall 25V-586 (Stellantis campaign 93C) covers free replacement. Symptoms include stalling at idle, no-start hot, and intermittent fuel pump prime noise from the rear of the vehicle. Failures cluster at 30,000-80,000 miles.
Alfa Romeo Stelvio(1 issue)
- Low-Pressure Fuel Pump Failure Causing Stall (Recall 25V-667)2018-2024
2018+ Stelvios can experience sudden engine stall or no-start due to a defective low-pressure fuel pump inside the fuel delivery module — same defect as the Giulia, same supplier, same NHTSA timeline. The pump's internal commutator wears prematurely and loses contact, cutting fuel supply at any speed. NHTSA recall 25V-667 (Stellantis campaign 93C) covers free replacement. Failures cluster at 30,000-80,000 miles; stalls reported at highway speed make this safety-critical until repaired.

What does P0230 mean on Alfa Romeo?▼
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 Alfa Romeo specifically, this code is documented across 2 models.
