Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

• Check the gas cap: a loose or damaged cap is a common trigger and is quick to fix.
• Look for obvious signs: low fluid levels, visible leaks, or unusual engine noises before driving farther.
• Note symptoms: loss of power, stalling, or smoke — record these for the technician.
• If the light is flashing, stop driving and call us — a flashing light often signals a severe misfire.
• For warranty protection and accurate diagnosis, have any needed repairs performed at a certified dealership like Coggin Toyota at the Avenues.
