Is There a Difference Between a Flashing Engine Light and a Steady Engine Light?
long story short, a steady light is a warning; it means something is wrong or about to go wrong, but it's not an emergency. It could be as simple as a sensor replacement. In most cases, a blinking light is bad. It could be overheating or an oil pressure issue. If your check engine light is blinking, get to your trustworthy mechanic, your minor annoyance/concern just got elevated...
Can You Drive with Engine Light Blinking?
Please do NOT. You cannot keep driving the car. Pull over and call a tow. It often indicates a misfire and if you keep driving you will most likely cause irreversible damage to your vehicle. Please do yourself a favor and pull over if this ever happens to you.
Why is My Check Engine Light On?
