P0230 on Toyota
Fuel Pump Primary Circuit Malfunction
P0230 on Toyota vehicles indicates fuel pump primary circuit malfunction. Au7o has documented this code across 3 Toyota models — most commonly on Camry, Corolla, RAV4. 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 Toyota by Model
Toyota Camry(1 issue)
- Low-Pressure Fuel Pump Failure (Recall)2018-2021
Toyota issued a recall for the low-pressure fuel pump which can fail and cause the engine to stall or not start. The fuel pump impeller may deform, leading to reduced fuel delivery. This affects many Toyota models.
Toyota Corolla(1 issue)
- Fuel Pump Impeller Deformation2018-2020
Certain 2018-2020 Corollas have a low-pressure fuel pump with an impeller that can deform due to excessive fuel absorption. This can cause reduced fuel delivery, engine hesitation, and in worst cases, engine stalling while driving - creating a significant crash risk. This is a safety recall affecting multiple Toyota models.
Toyota RAV4(1 issue)
- Low-Pressure Fuel Pump Failure / Engine Stall2019-2021
The low-pressure fuel pump inside the fuel tank may fail, causing the engine to stall while driving. This increases the risk of a crash, especially at highway speeds. Part of a massive Toyota recall affecting multiple models.

What does P0230 mean on Toyota?▼
P0230 stands for "Fuel Pump Primary Circuit Malfunction."

On Toyota specifically, this code is documented across 3 models.
