Car Check Engine Light Flashing
Overview
The check engine light is a dashboard indicator that illuminates when the engine control module (ECM) detects a problem with the engine or its emissions control system. A flashing check engine light is a more serious issue than a steady check engine light, and it indicates that there is a problem that needs to be addressed immediately.
There are a number of different reasons why the check engine light may flash, and the exact cause will vary depending on the make and model of your vehicle. However, some of the most common causes of a flashing check engine light include:
- Misfire
- Fuel system problem
- Ignition system problem
- Emissions control system problem
What to Do if Your Check Engine Light is Flashing
If your check engine light is flashing, it is important to take action immediately. Continuing to drive with a flashing check engine light can cause serious damage to your engine. The best thing to do is to pull over to a safe location and turn off your engine. Once your engine is off, you can restart it and see if the check engine light is still flashing. If the light is still flashing, you should call for roadside assistance or have your vehicle towed to a repair shop.
How to Fix a Flashing Check Engine Light
The only way to fix a flashing check engine light is to address the underlying problem. This may involve replacing a faulty part, such as a spark plug or fuel injector. In some cases, it may be necessary to reprogram the ECM. The best way to determine the cause of a flashing check engine light is to have your vehicle diagnosed by a qualified mechanic.
