Flashing Check Engine Light in a Toyota Sienna
When the check engine light in a Toyota Sienna is flashing, it indicates a serious issue that requires immediate attention. A flashing check engine light is different from a steady glow, and it typically signifies that the vehicle’s engine is in significant trouble and prompt service is necessary.
A flashing check engine light is almost always correlated with engine misfires, which means that the engine is dumping uncombusted fuel into the car’s exhaust system.

However, in the case of a flashing check engine light, it is best not to drive the vehicle and to schedule Toyota service immediately.
In summary, a flashing check engine light in a Toyota Sienna indicates a serious issue with the vehicle’s engine that requires immediate attention and service. It is not advisable to drive the vehicle when the check engine light is flashing.
