Toyota Engine Maintenance Required with P268111 or P268115. See the manufacturer document, vehicle conditions, exclusions and questions for a qualified shop before assuming a repair.
This is a research summary of a manufacturer communication, not a diagnosis for your car, a DIY repair procedure or confirmation of warranty or recall eligibility. No qualified technician has approved a repair for your individual vehicle here.
This historical communication is conditional. The current revision, VIN/build eligibility, measured diagnosis and any warranty or recall decision are not established here. Ask the manufacturer or a qualified shop to check the complete current document.

What prompted this manufacturer document
- Engine Maintenance Required displayed in the MID with a listed DTC
- Toyota treats this message/code combination as a coolant flow-control fault, not merely a routine oil-service reminder.
Which vehicle conditions must be checked
Each row below retains its own conditions. Do not combine engines, years or models across rows to create new applications. A listed model is not proof that a particular VIN is affected.
- Toyota Avalon Hybrid · 2019, 2020, 2021 · A25A-FXS; HEV
- Toyota Avalon · 2021 · A25A-FKS; gasoline
- Toyota Camry · 2018, 2019, 2020, 2021 · A25A-FKS; gasoline
- Toyota Camry Hybrid · 2018, 2019, 2020, 2021 · A25A-FXS; HEV
- Toyota Corolla · 2019, 2020, 2021 in the bulletin table; 2019 body/engine pairing needs VIN confirmation
- Toyota Corolla Hatchback · 2019, 2020, 2021 · M20A-FKS; gasoline
- Toyota RAV4 · 2019, 2020, 2021 · A25A-FKS; gasoline
- Toyota RAV4 Hybrid · 2019, 2020, 2021 · A25A-FXS; HEV
- Toyota RAV4 Prime · 2021 · A25A-FXS; PHEV
- Toyota Highlander Hybrid · 2020, 2021 · A25A-FXS; HEV
- Toyota Sienna Hybrid · 2021 · A25A-FXS; HEV
- Toyota Venza Hybrid · 2021 · A25A-FXS; HEV
- The document groups 2019 Corolla with M20A-FKS. U.S. sedan-versus-hatch model naming requires VIN verification; do not infer a 2019 sedan engine.
- The bulletin's grouped model/year table was visually checked in the original PDF on 2026-11-01; a 2019 Corolla sedan engine pairing still needs VIN/body confirmation.
Codes recorded in this document
A root listed only as an appearance has no separately verified meaning here. Preserve every suffix and module name; a shared root does not transfer a repair branch to another vehicle.
| Root | Raw form | Meaning in this source, if established |
|---|---|---|
| P2681 | P268111, P268115 | Coolant bypass-valve circuit shorted to ground; Coolant bypass-valve circuit open or shorted to supply |
What an owner can record safely
- Exact message rather than paraphrased maintenance reminder
- Full seven-character code
- Any coolant loss or overheating
Editorial safety boundary for this system
Overheat or persistent coolant loss takes priority over a slow-warm-up code.
- Use current model-specific service information, calibrated equipment and a qualified technician for the selected diagnostic branch.
- Do not open a hot pressure cap. Check only externally visible levels when cold and permitted by the manual.
This is a conservative editorial policy, not a manufacturer safe-to-drive decision for a specific vehicle.
What the source does not prove
- Do not reset the maintenance reminder and assume this electrical fault is repaired.
- A code or message alone does not establish a failed part, a safe-to-drive decision or an approved repair for this VIN.
- A service bulletin is not automatically a recall or free warranty repair. Confirm current eligibility directly.
Questions for the repair shop
- Which current manufacturer procedure, VIN/RPO/build gate and test result determine the diagnostic branch?
- Does a later revision or a current recall change the source's original advice?
- What measurement or inspection confirms the cause, and how will the repair be verified?
Open source-review issue
- Q3-11: 2019 Corolla naming with M20A-FKS requires body/VIN verification. Do not infer a 2019 U.S. sedan engine from the grouped Corolla/Hatchback rows.
The uncertain field is not used here to claim a current fitment, repair or market-wide failure.
