Few things catch a driver’s attention faster than the check engine light. Whether it turns on during a commute through Cleveland traffic or starts flashing on your way home, that small warning can bring big questions. Is it serious? Is it safe to keep driving? At Annie’s Auto in Cleveland, OH, we help take the guesswork out of check engine light diagnostics with honest answers and high-quality repairs for most makes and models.

Check Engine Light Diagnostics in Cleveland, OH

The check engine light is part of your vehicle’s onboard computer system. When something isn’t working the way it should, whether it’s affecting performance, emissions, or fuel efficiency, the system stores a trouble code and turns the light on to alert you. Sometimes the issue is minor, but other times it can signal a problem that may lead to extensive damage if ignored.

The important thing to note is that not all check engine lights mean the same thing. A steady light often points to an issue that should be checked soon, while a flashing light can indicate a more urgent problem that needs immediate attention. Common causes include faulty sensors, ignition issues, fuel system concerns, emission-related problems, or loose or damaged components.

Drivers in Cleveland may notice symptoms such as:

• Reduced fuel mileage
• Engine hesitation or rough idling
• Sluggish acceleration
• Stalling or difficulty starting
• Unusual engine noises or vibrations
