P0230 on Nissan by model: symptoms, diagnosis and fix
Nissan issued two recalls for fuel pump issues on certain 2019 Altimas. Recall 19V316000 covers front-wheel-drive 2.5L cars whose fuel pump lock ring may not be fully engaged, which can let fuel leak and raise the risk of fire. Recall 18V922000 covers cars whose retainer clip between the low-pressure fuel tube and the high-pressure fuel pump may not be locked; the tube can shift and leak fuel, or disconnect and stall the engine.
Common Symptoms
- Fuel odor or visible fuel leak
- Engine stalls while driving
- Engine won't start
How to Fix
Check if your VIN is covered by recall 19V316000 or 18V922000. Nissan dealers will inspect the fuel pump lock ring and tighten it (or replace the fuel pump if the ring is detached), or lock the fuel tube retainer clip, free of charge.

Frequently asked questions
What does P0230 mean on a Nissan?
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 Nissan it is documented across 1 model: Altima.
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.
