P0230 on Genesis
Fuel Pump Primary Circuit Malfunction
P0230 on Genesis vehicles indicates fuel pump primary circuit malfunction. Au7o has documented this code across 2 Genesis models — most commonly on GV70, GV80. 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)
P0230 on Genesis by Model
Genesis GV70(1 issue)
- Low-Pressure Fuel Pump Impeller Failure Causing Stalling2022-2023
The low-pressure fuel pump assembly can contain an impeller made from material that does not meet specification. Under high ambient temperatures the impeller deforms and interferes with the pump housing, creating mechanical resistance that shuts the pump down and starves the engine of fuel. The result is a sudden loss of motive power or an engine stall while driving, which can happen at speed and create a crash risk. Genesis addressed it under safety recalls 016G and 022G (NHTSA 23V-630 and 24V-282), covering 2022-2023 GV70 along with G80/GV80/G90.
Genesis GV80(1 issue)
- Low-Pressure Fuel Pump Impeller Deformation Causes Stalling (Recall 022G / NHTSA 24V282)2022-2023
The low-pressure fuel pump impeller can deform under high ambient temperatures, causing it to interfere with the pump housing and shut down. Symptoms include rough idle, hesitation/stumbling, MIL illumination, and engine stall while driving. Genesis recalled ~31,440 GV70/GV80/G80/G90 vehicles; GV80 production dates Nov 4 2021 through Sep 13 2022.

What does P0230 mean on Genesis?▼
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 Genesis specifically, this code is documented across 2 models.
What causes P0230 on Genesis vehicles?▼
Common causes on Genesis: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0230 on a Genesis?▼
Repair costs vary widely depending on the root cause and specific Genesis model.
Which Genesis models have P0230 documented?▼
Au7o has documented P0230 on 2 Genesis models: GV70, GV80.
