What to Do When Your Engine Light is Flashing: 1 Minute to Understand and Act on Your Engine Warning

If your engine light is flashing, it’s a sign that something urgent needs your attention. Ignoring it could lead to severe damage or costly repairs down the line. So, what should you do? First, let’s decode what this flashing light really means.

A flashing engine light typically indicates a severe engine problem, possibly related to the ignition system or emissions systems. You might also be experiencing misfires, which can create hazardous emissions and reduce your fuel efficiency.

Check for Additional Signs:

While the engine light is a primary warning, it often comes accompanied by other symptoms. Did you notice a rough idle? Is there a change in your car's performance, such as hesitation or stalling? Pay attention to these signs, as they might point towards specific issues that need addressing.

If the light is flashing, it’s a good idea to pull over and turn off your engine as soon as it’s safe to do so. Continuing to drive could worsen the problem, leading to more significant damage and potential repair costs.

Take Action:

Once you've pulled over, you can take a few preliminary steps. Check your oil levels and coolant. Sometimes, low fluids can trigger the check engine light. If everything seems alright, don’t hesitate to call a mechanic or tow your vehicle to avoid further damage.

Diagnosing the Issue:

Your mechanic will use an OBD-II scanner to read the error codes stored in your vehicle’s computer. These codes can help identify the issues triggering the flashing light. Common causes include faulty spark plugs, a malfunctioning fuel injector, or problems with the catalytic converter.
