Decoding the Check Engine Light: Understanding its Significance and Warnings

The malfunction indicator lamp, most commonly known as the check engine light, and often represented by an engine shaped icon, is an essential component of your car’s OBD II port in your onboard diagnostics system. This light means that the engine management system has detected a possible issue with one or more components of your vehicle.


Contrary to commonly held beliefs, the check engine light can indicate problems beyond just the engine itself. This warning light may come on due to issues impacting a range of systems, including the emissions system, fuel system, ignition system, and more.


While the check engine light is one of the most common dashboard warning lights, your car’s dashboard can display a variety of other warning lights, such as the maintenance required light, service engine light, and more. Each of these lights serves a specific purpose, alerting you to different issues that require attention.


So, before you start worrying about expensive repairs, it’s essential to understand that the light could be activated by something as simple as a loose gas cap. While some of them may be minor, others require immediate attention.


Here are some common causes for check engine light activation:

Loose Gas Cap

One of the most common and benign reasons for the check engine light to come on is a loose gas cap. That is right; something as simple as a loose gas cap can trigger the warning. The gas cap helps maintain the pressure in the fuel tank, and when it’s loose or damaged, it can lead to fuel vapor leakage. Our expert technicians and machinists at Jensen Auto Service will quickly check and tighten the gas cap, making sure the light turns off.

Faulty Oxygen Sensor

The oxygen sensor is crucial in monitoring the level of oxygen in exhaust gases. It helps the engine control module or ECM, adjust the air fuel mixture for optimal performance and emissions. A defective oxygen sensor can lead to decreased fuel efficiency and increased emissions. At Jensen Auto Service, we use advanced diagnostic tools to identify and replace malfunctioning oxygen sensors.

Issues with the Catalytic Converter

The catalytic converter transforms the dangerous pollutants from your vehicle’s exhaust system into less harmful substances. If your catalytic converter gets broken or damaged, it can cause a surge in harmful emissions and affect your engine’s performance. Our seasoned technicians and machinists will inspect and replace the faulty catalytic converters, ensuring your vehicle meets emissions standards.

Problems with the Mass Airflow Sensor

The mass airflow sensor is a system that calculates the amount of air that enters the engine. A malfunctioning mass airflow sensor can cause rough idling, reduced power, and poor fuel efficiency. We specialize in diagnosing and repairing issues with the mass airflow sensor, restoring your car’s performance.

Issues with the Emissions System

When your car’s emissions system encounters problems, it has the potential to trigger the dreaded check engine light, signifying that something isn’t quite right under the hood. Emissions related issues can range from a loose gas cap to a faulty oxygen sensor, a failing catalytic converter, or even problems with the evaporative emission control system.

Spark Plug and Ignition Coil Problems

Faulty spark plugs or ignition coils can result in engine misfires, reduced power, and increased exhaust emissions. Our experienced team can quickly identify and replace damaged spark plug wires or ignition coils, ensuring smooth engine operation.

Vacuum Leaks

If there’s an unintended gap in the engine’s vacuum system, it results in a vacuum leak. This can negatively impact engine performance and make fuel consumption worse. Our technicians and machinists are experts in detecting and fixing vacuum leaks, optimizing your car’s performance.

Misfiring Engine

An engine misfire happens when the combustion process in one or more cylinders is interrupted, leading to inadequate ignition. The result is diminished performance, heightened fuel consumption, and potential catalytic converter damage. Disregarding an engine misfire can inflict severe harm to your engine, making it imperative to have it assessed without delay.

Flashing vs. Steady Alerts

When it comes to the check engine light on your car’s dashboard, two distinct signals demand your attention: the flashing check engine warning light and the steady check engine light. Both types signify different levels of severity and require prompt attention to ensure the vehicle’s optimal performance and safety. At Jensen Auto Service, whether your check engine light is flashing urgently or steadily, our diagnostic technicians and machinists are well-equipped to handle the situation with the utmost care and precision.

Flashing Check Engine Light

The flashing check engine light is a powerful indicator that requires immediate attention. When this light starts blinking, it signifies a severe problem with your car’s engine that demands urgent action. Ignoring a flashing check engine light can lead to further damage and expensive repairs.


If your check engine light is flashing, it could be due to several reasons, such as engine misfires, faulty ignition coils, or possible harm to the catalytic converter. If you encounter a blinking check engine light, it is crucial to pull over safely and have your car checked by a qualified technician and machinists as soon as possible.

Steady Check Engine Light

On the other hand, a steady check engine light is less severe than a flashing one but still requires prompt attention. A steady light suggests that your car’s engine management system has detected a fault or a potential issue with one of its components. While the problem may not be as immediate as with a flashing light, it should not be ignored.


When your check engine light is illuminating steadily, the causes may include a loose gas cap, faulty oxygen sensors, or issues with the vehicle’s exhaust system. Although driving with a steady check engine light may not be an immediate risk, neglecting the issue can result in reduced fuel economy and potential damage to other components.

From faulty sensors and misfires to issues with the fuel system or exhaust, the DTCs give us valuable clues to identify the root cause.

Comprehensive Inspection

After retrieving the DTCs, our technicians and machinists will conduct a thorough visual inspection of your car’s engine and emissions system. They diligently search for any visible signs of damage, loose connections, or worn out components that might be contributing to the check engine light activation. This thorough examination ensures that no potential issue goes unnoticed.
