Why is My Chevy Check Engine Lighting Flashing?
A steady check engine light means that your Chevy has detected a problem that needs attention. This can cause panic, but the check engine light does not always mean an urgent issue. Sometimes, it can indicate a loose connection or another relatively minor issue that can be addressed quickly.
A flashing check engine light, however, is more urgent. If the check engine light is flashing while you drive, your vehicle is warning you about a serious engine issue, often related to a misfire. A misfire happens when one or more cylinders are not firing the way they should. That can allow unburned fuel to enter the exhaust system, which may damage important components such as the catalytic converter. The safest move is to stop driving as soon as it is safe and schedule service at Colonial Chevrolet right away.
What Should I Do If My Chevy Check Engine Light Is Flashing?
If your Chevy check engine light starts flashing, take it seriously. Reduce your speed, avoid hard acceleration, and find a safe place to pull over. If the vehicle is shaking, running rough, losing power, or making unusual sounds, it is best not to keep driving. Just stop the vehicle and call a tow truck to bring the vehicle to get serviced.
Continuing to drive with a flashing check engine light can turn a repairable issue into a much more expensive problem. A timely professional diagnostic inspection can identify the cause and help prevent further damage.
Common Reasons for a Flashing Check Engine Light
A flashing check engine light can be caused by several issues, including:
- Engine misfire
- Worn spark plugs
- Faulty ignition coils
- Fuel delivery problems
- Sensor issues
- Emissions system problems
- Vacuum leaks
- Poor air/fuel mixture
How your vehicle is driving can give some cues to what might be causing the light, but the exact cause will be determined by the diagnostic trouble code stored in your vehicle's computer. The professional service technicians at Colonial Chevrolet will use this code to determine the best way to repair and protect your vehicle.
Flashing vs. Solid Check Engine Light
A solid check engine light usually means that your Chevy needs service soon. The vehicle may still drive normally, but the issue should not be ignored as it could grow into a more serious problem if it is left unaddressed.
A flashing check engine light is different. It means that the problem is serious enough to require immediate attention. If the light is flashing, especially if the vehicle is also shaking or experiencing rough performance, the vehicle should be inspected as soon as possible.
