Steady Light
If your check engine light comes on, pull over and see if your gas cap is loose. If it is, tighten it. If this doesn’t clear the check engine light in a few miles, bring your vehicle to your mechanic at your earliest convenience.
Lit with Noticeable Performance Issues
If the check engine light remains continuously lit and your vehicle is experiencing significant performance issues, there is likely an issue with a crucial part of your engine system or emissions control systems. Pull over, stop the engine, and arrange to have your vehicle towed to a repair shop to prevent further engine damage.
Steady Blinking Light
If your check engine light steadily blinks when you are accelerating, your vehicle’s emission control system is experiencing failure and causing the engine to misfire to the extent that your catalytic converter is being seriously damaged with every blink and could eventually catch fire. Pull over immediately and have your vehicle towed to a repair shop.
