P0230 on Infiniti
Fuel Pump Primary Circuit Malfunction
P0230 on Infiniti vehicles indicates fuel pump primary circuit malfunction. Au7o has documented this code across 1 Infiniti model — most commonly on QX80. 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.
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)

- Fuel Pump Impeller Swells and Binds Causing Engine Stall (Recall 21V373000)2020-2021
The impeller inside the fuel pump module can absorb fuel, swell, and bind against the pump housing. Once it binds the pump fails and fuel delivery stops, stalling the engine — potentially at speed and without warning. This is the same low-density impeller defect that ran through a large number of Nissan and Infiniti products of the period. NHTSA campaign 21V373000 covers 2020-2021 QX80 and Nissan Armada with V8 engines; owner letters were mailed February 4, 2022, and the campaign numbers are R21A3 for Infiniti and R21A2 for Nissan. The remedy is replacement of the fuel pump module, not a software change.
