The check engine light (CIL) is an on-board diagnostics device that helps you avoid significant engine failure. An illuminated light can signal various minor and serious problems, so getting your vehicle inspected by an auto mechanic will prevent further damage. Here's more information about what to do if the indicator appears.

Different Types of Lights

Flashing

If the light flashes, your engine is experiencing a significant problem, like a failing fuel injector, and you should pull over immediately. Reduce your speed and shift into the right lane and prepare to move to the shoulder. If the light remains steady, the matter is less urgent but should still be addressed as soon as possible.

Colored

On some models, the CIL turns red to indicate that the car shouldn't continue operating, while yellow represents standard, less pressing maintenance tasks, like low oil levels. Since the check engine light can signal multiple issues, have an ASE®-certified auto mechanic inspect the vehicle and run further diagnostics.

There are some steps you can take to rule out a faulty sensor. Tighten the gas cap to verify it isn't loose. If it was, the CIL should reset itself after driving several miles. Look for additional dashboard warning lights, and verify the gauge doesn't show your car is overheating.

Why You Should Visit an Auto Mechanic

Engine problems shouldn't be ignored because even minor malfunctions can cause severe issues. Once the light illuminates, have an experienced auto mechanic inspect your car, regardless if the indicator is blinking or yellow.

They'll run computer diagnostics to determine the warning's cause, then make the necessary repairs. These fixes typically include replacing faulty oxygen sensors, a defective ignition coil, or worn spark plugs and wires.
