Quick Answer: A solid check engine light means your vehicle’s onboard computer detected an emissions, fuel, or ignition issue that needs professional attention. However, a flashing check engine light signals a severe engine misfire that can cause expensive damage; pull over where it is safe to do so, turn off the engine, and tow your vehicle to The Four Car Garage in San Mateo.
It is hard to believe that the standardized OBD-II check engine light has been protecting drivers for over three decades. Few car owners look forward to seeing it illuminated on the dashboard, yet at The Four Car Garage, we know it is your vehicle's best early-warning system. Modern vehicles rely on dozens of sensors and computers processing data in real time, giving us the opportunity to catch minor issues before they turn into expensive engine repairs.
Why Is My Check Engine Light On?
Thousands of fault codes can trigger the check engine light – some of the most frequent culprits:
- loose or faulty gas cap
- failing oxygen sensor
- spark plugs
- ignition coils
- EVAP system leak
- EGR valve failure.
Code Reading vs. True Check Engine Light Diagnostics
Our San Mateo auto repair shop offers comprehensive check engine light diagnostics and repairs. Unlike the free code scans at auto parts stores, which only identify a general system fault, but don’t tell you what caused the issue, at The Four Car Garage our nationally ASE certified technicians will use state-of-the-art diagnostic tools and procedures to find the root cause of the problem.
Once we know the root cause, we will explain what failed, how it can be repaired, and what the cost will be. Once you approve the repairs, we will get your vehicle fixed, tested and ready for the road – usually the same day.
So if your vehicle’s computer turned on the check engine light, call The Four Car Garage to get your car back in top shape.
