Check Engine Light

What Does the Check Engine Light Mean?

The check engine light is part of your vehicle’s onboard diagnostic system. When the light comes on, it means the system has detected a problem. This might range from a small issue, such as a loose gas cap, to larger problems, like a failing catalytic converter.

The light usually falls into two categories:

• Steady Light: Indicates a less timely issue, but still one that needs to be diagnosed and repaired.
• Flashing Light: Signifies a larger problem, such as an engine misfire, which needs immediate attention to avoid further damage.

Common Causes of a Check Engine Light

There are a few reasons your check engine light might come on, but some causes are more common. At Germany’s Best, Inc., we diagnose and repair the following issues:

• Broken Gas Cap: A loose or damaged gas cap can cause a drop in pressure in the fuel system, triggering the light.
• Failing Catalytic Converter: The catalytic converter reduces harmful emissions, and a malfunction can lead to poor engine performance and increased pollution.
• Oxygen (O2) Sensor Issues: A faulty O2 sensor can disrupt the air-fuel mixture, meaning reduced efficiency and higher emissions.
• Low Battery Voltage: A weak or failing battery can trigger warning lights, including the check engine light.
• Low Engine Oil or Oil Pressure: Insufficient oil levels or pressure can harm engine parts and result in serious damage if not addressed.

Risks of Ignoring the Check Engine Light

While it might be tempting to ignore the check engine light if your car seems to be running fine, doing so can lead to more serious issues over time. Risks include:

• Increased Emissions: Problems like a failing catalytic converter or O2 sensor can lead to higher emissions, potentially failing a smog check.
• Decreased Fuel Efficiency: Issues that trigger the check engine light, such as air-fuel mixture problems, can reduce gas mileage.
• Engine Damage: Ignoring issues, like low oil pressure or engine misfires, can result in repairs or even engine failure.
