Toyota Camry (2018-2025): Flashing Check Engine Light
PULL OVER — Do Not Continue Driving
A FLASHING check engine light is an active engine misfire — unburned fuel is entering the catalytic converter, which will destroy it within minutes. This is fundamentally different from a solid check engine light (which means a stored fault code).
What you see: A flashing or blinking orange/yellow engine-shaped icon on the dashboard
What to Do Right Now
Pull over as soon as safely possible. Turn off the engine. Do NOT continue driving — a flashing CEL means raw fuel is dumping into the catalytic converter. The $200 diagnostic becomes a $2,000 catalytic converter replacement if you keep driving. Call a tow truck if needed.
