Check Engine Light Diagnostic

The Check Engine Light is an indicator on a vehicle's dashboard that alerts the driver to a variety of potential engine and emission system issues.

Check Engine Light Diagnostic explained

Check Engine Lights are warning signals illuminated on a vehicle's dashboard, designed to alert the driver of potential issues with the engine or related systems.

This light can be triggered by a range of problems, from minor issues like a loose gas cap to more serious concerns such as engine malfunctions or emission control problems. The light usually appears as an engine symbol or the words "Check Engine," and it can be either steady or flashing, depending on the severity of the issue.

At Gateway Auto - Service & Collision Center, our diagnostic services involve using specialized scanning tools to read the codes from the vehicle's onboard computer, which helps in identifying the specific issue triggering the light.

When or why do you need it?

A Check Engine Light Diagnostic is necessary as soon as the light appears on your dashboard. Ignoring this warning can lead to more significant and potentially costly issues.

A steady light often indicates a less urgent issue, while a flashing light suggests a more severe problem that should be addressed immediately to avoid damage to the engine or other critical components.

At Gateway Auto - Service & Collision Center, we recommend getting a diagnostic check promptly to accurately determine the cause of the alert. Our expert team will assess the issue, advise on the necessary repairs, and reset the light once the problem is resolved, ensuring your vehicle runs smoothly and efficiently.

Frequently asked questions

If it's a car, we'll fix it. If it's a question, we'll answer it.

Are your technicians trained and certified to diagnose complex, modern vehicles?

Yes! Our team is made of up ASE certified master technicians with decades of industry experience. They carry a wealth of knowledge, as well as the updated tools and training to diagnose modern vehicles with their complex computer systems.

Is it safe to drive my car if the check engine light is on but not flashing?

If the check engine light is on steadily and not flashing, it generally indicates a less severe issue. While it may be safe to drive in some cases, we recommend scheduling an appointment for a diagnostic check to identify and address the problem promptly, thus preventing more serious damage or safety risks.

Can I check the engine codes myself using an OBD-II scanner?

While you can use an OBD-II scanner to retrieve engine codes, the codes only provide a starting point for diagnostics and do not necessarily pinpoint the exact problem. Our certified technicians have the expertise and tools to interpret the codes accurately and perform a comprehensive diagnosis.

Why is my check engine light flashing?

If the check engine light is flashing, it indicates a severe problem that requires immediate attention. In such cases, it's best to pull over safely and have the vehicle towed to the shop for diagnostics.

What does it mean if my "check engine" or "service engine soon" light comes on?

There are many electronic components and sensors that manage your vehicle's emissions and performance. When one of these fails, the "check engine" light or "CEL" is illuminated (commonly yellow) on your dashboard. Although your car may seem to run or drive fine, it is important to have the issue addressed to prevent damage from occurring. There are times when a check engine light is a simple fix, and others where it is a much more serious problem.
