Check Engine Light Flashing

The check engine light flashing on a 2025 Toyota Corolla is a critical indicator that an engine misfire or severe condition may be occurring. A flashing light typically means the engine is misfiring and unburned fuel could be entering the exhaust stream — a situation that can damage the catalytic converter and rapidly increase repair costs if left unchecked. At Stevinson Toyota West in CO, our priority is protecting your vehicle and your budget: we recommend immediate inspection when a light flashes. Our technicians use Toyota-approved diagnostics to pinpoint ignition coils, fuel injectors, or sensor failures and offer repair paths that restore performance and fuel efficiency. We always explain costs up front, and our use of OEM parts and factory-trained service teams reduces the chance of repeat visits — delivering immediate savings and better long-term value. Check our current service specials, and when you’re ready to act, schedule service online or contact our service department for rapid assistance.
