What Should You Do When Your Check Engine Light Comes On?

At Marv and Mike's Auto & Tire in Rockville, MD, we understand how alarming it can be when your check engine light suddenly illuminates on your dashboard. This small warning light can signal a range of issues, from minor problems to serious engine malfunctions. To help you navigate this situation, we’ve compiled a detailed look at what actions you should take when your check engine light comes on.

Understanding the Check Engine Light

The check engine light is part of your vehicle’s onboard diagnostics system (OBD). When this light comes on, it means that your car’s computer has detected a problem. While it can be tempting to ignore the light, doing so can lead to more significant issues down the road. The key is understanding what this light can indicate and taking appropriate action.

Common Reasons for a Check Engine Light

There are several reasons why your check engine light might turn on. Here are some of the most common causes:

1. Loose or Faulty Gas Cap: Surprisingly, a loose or damaged gas cap can cause your check engine light to come on. The gas cap seals the fuel system and maintains pressure. If it's not secure, it can trigger the light.
2. Oxygen Sensor Issues: The oxygen sensor monitors the amount of unburned oxygen in the exhaust and helps manage fuel efficiency. A faulty sensor can reduce gas mileage and increase emissions.
3. Catalytic Converter Problems: The catalytic converter helps reduce harmful emissions. Issues with this part can be serious, leading to increased pollution and reduced performance.
4. Spark Plug or Ignition Coil Issues: These components are crucial for your engine’s operation. Problems here can cause your engine to misfire, reducing performance and efficiency.
5. Mass Airflow Sensor Issues: This sensor measures the air entering the engine to ensure optimal fuel-to-air ratio. A malfunction can affect fuel efficiency and engine performance.

Immediate Steps to Take

When your check engine light comes on, follow these steps to determine your next move:

1. Check for Serious Issues: If the check engine light is flashing, this indicates a severe issue that requires immediate attention. Pull over safely and call Marv and Mike's Auto & Tire for assistance. A flashing light often means a misfire, which can damage the catalytic converter if not addressed promptly.
2. Inspect the Gas Cap: Check if the gas cap is loose or damaged. Tighten it if necessary and see if the light goes off after driving for a while.
3. Reduce Speed and Load: If the light is steady but not flashing, reduce your speed and avoid heavy loads to minimize strain on the engine. This can help prevent further damage until you can get the vehicle checked.
4. Schedule a Diagnostic Check: Contact Marv and Mike's Auto & Tire in Rockville, MD, to schedule a diagnostic check. Our ASE-certified technicians will use advanced tools to read the error codes and pinpoint the exact issue.
