Check Engine Light - What Is the Check Engine Light?
The check engine light is a dashboard warning. It's part of your car's onboard diagnostics system and pops up when the computer senses something's off with emissions or engine performance.
You'll see it as a tiny engine icon or the words "CHECK ENGINE." Sometimes it's yellow, orange, or even red, depending on how serious the problem is.
If your check engine light comes on, you usually don't need to panic or pull over—unless it's flashing. A steady light means you should get it checked soon. A flashing light? That's your cue to get help right away.
Warning Signs - What Triggers the Check Engine Light?
Other common triggers include:
- Faulty spark plugs or wires
- Mass airflow sensor failures
- Bad ignition coils
- EGR valve issues
- Vacuum leaks
- Battery or charging system problems
Missouri's wild temperature swings can sometimes mess with your sensors, causing temporary warnings. Still, we'd never tell you to ignore the light.
When it pops on, your car's computer has picked up something unusual. It could be nothing major—or it could be serious. You won't know until you check it out.
If your check engine light comes on in Maryland Heights, swing by and let us take a look. It's better than waiting for a small issue to turn into a headache.

Our Expertise - What Does the OBD-II Scanner Do?
An OBD-II scanner is a diagnostic tool we use at Quality Auto Repair Tire & Auto Sales. It helps us figure out what's going on inside your car when that pesky check engine light pops up.
You plug the scanner into your car's OBD-II port, which is usually hiding under the dashboard near the steering column. Once it's connected, the scanner talks straight to your vehicle's computer system.
But that's not all our scanners can do:
- Show real-time engine data
- Keep an eye on emission systems
- Check how the fuel system's doing
- Test oxygen sensors
- Reset the check engine light once we've made repairs
