What Does Your Check Engine Light Mean?

What does it mean when you see the check engine light flashing on your vehicle’s dashboard? It could appear as an engine symbol or the words “check engine” spelled out, but either way, it indicates an issue with your vehicle that should be addressed right away. Learn more about why your check engine light may be on, and what you can do about it with the Mercedes-Benz Burlington’s service team.

Possible Check Engine Light Causes

The check engine light is part of your vehicle’s diagnostics system that activates when a problem is detected. Any of the following issues could be why your Mercedes-Benz check engine light is on:

• Loose Gas Cap — Actually, not all causes of a check engine light are serious. You might simply need to tighten the gas cap! If you tighten your gas cap and the engine warning light remains on, you’ll need to bring your vehicle in for service.
• Spark Plugs — If you wait too long to replace your spark plugs, it can trigger the Mercedes-Benz check engine light. If you need your spark plugs replaced, you can find replacements at the Mercedes-Benz Burlington parts centre.
• Mass Airflow Sensor — Failing to replace your vehicle’s air filter is another reason your engine warning light may be on. During your regular Mercedes-Benz maintenance visit, our team can check the condition of your filter and replace it if needed.
• Oxygen Sensor — Faulty oxygen sensors are another reason that your check engine light might turn on. You’ll want to replace your oxygen sensor immediately; neglecting to do so could damage your catalytic converter.
• Catalytic Converter — The catalytic converter can overheat as a result of a faulty oxygen sensor. This will require the care of the Mercedes-Benz Burlington service centre.

What To Do When Your Mercedes-Benz Check Engine Light Turns On

If the check engine light appears, it’s crucial to have the vehicle checked over by a mechanic. However, the way in which the check engine light appears may indicate an emergency.

• A blinking light may point to an engine misfire that can cause significant damage to your engine. In this case, you need to have your vehicle looked at as soon as possible.
• A steady light usually means the problem isn’t an immediate emergency, but you still should schedule a service appointment as soon as you can.

Of course, the meaning of the check engine light and the way it appears varies by model. Make sure to consult your Mercedes-Benz owner’s manual for more information.
