Check Engine Light
What Does the Check Engine Light Mean?
The Check Engine light isn’t something you’re thrilled to see, but it’s an essential warning about potential issues with your engine, exhaust system, or battery.
Modern vehicles use the On-Board Diagnostics (OBD) system, which monitors emissions and triggers the Check Engine light for a variety of problems, ranging from a loose fuel cap to a failing catalytic converter.
Don’t ignore it. Serra Traverse City Technicians are OBD II experts. We’ll decode your Check Engine light, explain the issue, and provide a written estimate before making any repairs.
Why Is My Check Engine Light On?
The light usually signals an issue with one or more engine or exhaust system components, such as:
- Oxygen sensor
- Catalytic converter
- Mass airflow sensor
- Spark plugs or wires
Other possible causes include:
- Loose or faulty gas cap
- Vacuum leak
- Exhaust gas recirculation (EGR) valve failure
- Dead battery
- Malfunctioning aftermarket car alarm
Solid vs. Flashing Check Engine Light
- Solid light: Diagnose it as soon as possible.
- Flashing light: Head to a service station immediately—it could indicate a severe issue.
What About the Light at Startup?
It’s normal for all dashboard lights, including the Check Engine light, to turn on briefly during startup. This is a system check, confirming all indicators are functional and revealing any burned-out bulbs.

How to Respond to a Check Engine Light
The appropriate response to a Check Engine light depends on your vehicle and the light’s behavior:
- Flashing Check Engine Light:
- Pull over immediately and call for a tow.
- Continuing to drive could damage your engine and catalytic converter.
- Flashing Then Solid Light:
- Even if the light stops flashing, have your vehicle serviced immediately.
- Steady Check Engine Light:
- Schedule an appointment with a mechanic as soon as possible.
- There are many potential causes for the light.
- Light Still On After Service:
- It’s okay to wait a few days to see if the light resets itself.
- If it stays on, contact Serra Traverse City to confirm that the issue has been resolved.
A Quick Fix to Try:
- Check for a loose fuel cap.
- Tightening the cap may resolve the issue, and the light should turn off. If it does, you’re good to go!
