A flashing check engine light can be scary, but it doesn’t necessarily mean you’re in for an enormous repair bill. Here’s how to figure out what the light means and what you should do when you see the check engine light on your car’s dashboard
What does the check engine light mean?
While the check engine light can mean a serious issue with your engine, it often means a small issue that needs your attention to avoid further damage. This could include a fuel cap that has not been replaced properly, low oil pressure or a blown spark plug.
Depending on your car’s model, the light might be orange or blinking if there is a minor issue. It might be a red light or a light that keeps burning (without blinking) for more severe issues. The best is to consult your car’s owner’s manual to understand how problems are indicated.
What to do if your check engine light goes on
Once you notice the check engine light, stop at a safe place as soon as possible. Be sure to turn on your emergency indicators and set out your emergency triangle to increase visibility if you are in an area where traffic is moving around you.
If the area is safe enough for you to get out of your car, call someone close to you and let them know where you are and what’s happening before you start digging around for the problem. Grab your owner manual and check for a “FAQ” section or information on what the different lights on your dashboard could mean. If you have a newer model car, there might be a diagnostic option that you can run inside the vehicle. Start by checking if all the caps on your car are closed and tightened. Check the fuel cap. Access the engine and check if everything seems to be connected and in the right place. Look out for disconnected hoses or loose belts.
The Engine Light Turned On. What Caused It?
The engine light turned on, and you checked that the fuel cap is closed tightly. But why is my check engine light flashing despite this, you wonder? Other engine parts need to be checked and replaced if necessary, as that might be why the check engine light comes on. What else could cause the error?
- Catalytic converter
- Fuel injector
- Faulty oxygen sensors
- Faulty mass airflow sensor
- Ignition coil
- Spark plugs
- Damaged thermostat
- Evaporative emissions (EVAP) purge control valve
- Evaporative emissions (EVAP) purge solenoid.

Do Electric and Hybrid Vehicles Have An Engine Light?
Now that you know the reasons the check engine light comes on, do you wonder if electric and hybrid vehicles have the same warning light? Electric Vehicles (EV) don’t have engines, but they have what could be termed a check engine light in some models. This EV warning light features an exclamation point over a car. It could indicate an issue with the cooling system, shift control system, traction motor and inverter system, charge port, charge, or lithium-ion battery.
There are three categories of warning lights in hybrid and electric vehicles.
Red warning light. Signifies a serious problem and the car must be stopped as soon as it is safe to do so.
Amber warning light. Action required, but you don’t have to stop immediately.
Green/Blue/Black warning lights. For information only and don’t require an action.
What if you’ve checked all of these parts and the check engine light is still on? Then you might need to call roadside assistance to determine whether your car needs to be towed before you attempt to switch the engine again.
