The check engine light is part of your car’s internal diagnostics system. If your check engine light is aglow on your dashboard, don’t panic, there is nothing to fear. Its purpose is to warn you of a potential problem that your vehicle’s diagnostic system is unable to fix on its own. An issue with spark plugs or wires, the oxygen sensor, or even a loose gas cap can trigger the check engine light. A glowing light doesn’t mean you have to change course and immediately drive your car to your mechanic, but it does mean you should get it checked as soon as possible.
However, if the light is flashing the issue is more serious and must be taken care of right away. A flashing check engine light is a sign that the engine is misfiring which means that a cylinder is not combusting the fuel and air to push the piston down every time it’s supposed to. This should be checked ASAP to prevent severe and expensive damage to the catalytic converters.
Even if your car seems to be running smoothly, ignoring the warning light could result in costly repairs. Performing scheduled maintenance checks and addressing these warning lights in a timely fashion can help keep your vehicle’s safety, fuel economy and longevity in check.
