What Does a Flashing Check Engine Light Mean?

When you're driving on the road, nothing is more unsettling than a flashing check engine light. While a steady light may indicate a minor issue, a flashing check engine light typically means there's a severe problem with your vehicle that needs to be addressed immediately. Ignoring a flashing check engine light could lead to more severe damage to your car and more expensive repairs down the line.

A flashing check engine light is a tell-tale indication that your vehicle's engine is misfiring. The indicator means that one or more cylinders aren't firing properly, causing unburned fuel to be dumped into the exhaust system. This can cause damage to your catalytic converter and other parts of your vehicle's emission control system.

Some common explanations for a flashing check engine light include a faulty spark plug or ignition coil, a clogged fuel injector, or a malfunctioning oxygen sensor. These issues need to be addressed by a mechanic as soon as possible to prevent further damage to your vehicle.

In some cases, a flashing check engine light may also indicate a more severe problem with your vehicle, such as a damaged engine control module or a failing catalytic converter. These issues can be more expensive to repair, so it's important to get your car checked out right away to prevent further damage and costs.

A flashing check engine light is a sight that most people don't want to see but something to never ignore. It's a sign that there's a serious problem with your automobile that needs to be looked at by a professional technician as soon as possible. Please bring your vehicle to Preferred Auto & Fleet Service if your car needs check engine light diagnostics and repairs.
