P0230 on Toyota by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Engine hesitation or loss of power during acceleration
- Engine stalling while driving
- Difficulty starting the vehicle
- Check engine light illumination
How to Fix
Replace fuel pump assembly with improved part (covered under recall).

Toyota's Denso low-pressure fuel-pump recall history includes certain 2018-2020 Camry vehicles under original NHTSA recall 20V012 / Toyota 20TA02 and a small omitted population of 2018 Camrys under 25V028 / 25TA01. An affected pump can stop operating, causing warning messages, rough running, engine stall and inability to restart; a stall at higher speed increases crash risk. Applicability depends on the VIN and specific pump population, not model year alone. The prior 2021 scope and recall numbers 20V750/21V251 were incorrect.
Common Symptoms
- Warning lights or messages
- Rough engine running
- Engine stall
- Engine may not restart after the pump stops
How to Fix
Check the VIN at Toyota's official recall lookup or with a Toyota dealer. If an applicable campaign is open, the dealer replaces the involved low-pressure fuel pump with an improved pump free of charge. If the engine runs rough, warning indicators appear or the vehicle begins losing power, move out of traffic and stop safely; if it stalls, do not rely on it restarting. Do not select a pump or treat P0087/P0230/P0231/P0232 as recall eligibility criteria from this card.
Owner tips & cautions
- WarningRecall eligibility is VIN-specific. Do not buy a pump or infer inclusion from the model year, symptoms or a generic fuel-system DTC.
- TipAsk Toyota to confirm both 20TA02/20V012 and 25TA01/25V028 status for the VIN and document completion of the free improved-pump remedy.

Frequently asked questions
What does P0230 mean on a Toyota?
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 Toyota it is documented across 2 models: Corolla, Camry.
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.
