Engine Check Warning: How Hogan Tire & Auto Can Help

July 7, 2025 Hogan Tire & Auto

If your car’s check engine light illuminates, it can be a cause for concern. This simple warning can signal a variety of issues, from something as minor as a loose gas cap to more significant engine problems like a failing catalytic converter or a malfunctioning mass airflow sensor.

Regardless of the reason, it’s important to address the warning promptly to prevent more expensive repairs down the road. At Hogan Tire & Auto, with eight convenient locations across Massachusetts, we offer comprehensive diagnostic services to help you understand the issue and fix the problem.

What Does The Check Engine Light Mean?

The check engine light is part of your vehicle’s onboard diagnostics system. This system is designed to monitor various components of your car engine, including its emissions systems and other vital components that ensure smooth operation. When the diagnostic system detects an issue, it triggers the warning light to alert you.

Some common reasons the check engine light illuminates include:

Loose gas cap: One of the simplest issues but also the most common. A loose or damaged gas cap can cause fuel vapors to escape, triggering the warning light.
Oxygen sensor failure: The oxygen sensor monitors the level of oxygen in the exhaust and helps regulate the engine’s fuel consumption. If it fails, your car’s performance can drop, and your fuel efficiency may suffer.
Spark plugs: Worn or damaged spark plugs can cause your engine to misfire, triggering the check engine light and possibly affecting fuel efficiency and overall performance.
Mass airflow sensor issues: This sensor monitors the amount of air entering the engine. If it becomes faulty, your car may experience poor acceleration, rough idling, or reduced fuel efficiency.

Common Diagnostic Codes And Trouble Codes

When your check engine light comes on, your vehicle’s onboard diagnostics (OBD) system records a trouble code. This code is used to pinpoint the source of the issue. Some common diagnostic codes include:

P0300: This code indicates a random misfire in your engine, which can be caused by several issues, such as faulty spark plugs or a clogged fuel injector.
P0420: This code typically points to a problem with the catalytic converter, which helps reduce harmful emissions from the engine. A faulty converter can significantly affect your car’s performance.
P0171: This code is triggered by an issue with the air/fuel mixture, often related to a malfunctioning mass airflow sensor or a vacuum leak.

By using a scan tool, our expert technicians can read these trouble codes and get a clearer picture of what’s going on with your vehicle. From there, we can take the necessary steps to fix the problem and get your car back running smoothly.

Why Regular Maintenance Is Key

Regular maintenance is the best way to avoid engine problems and prevent your check engine light from turning on unexpectedly. At Hogan Tire & Auto, we recommend following your vehicle’s maintenance required schedule, which typically includes things like:

Oil changes: Regular oil changes are crucial for maintaining proper oil pressure and ensuring that the engine runs efficiently.
Spark plug replacement: Over time, spark plugs wear down and can cause misfires. Regular inspections and replacements will help maintain optimal engine performance.
Emissions system checks: Ensuring your catalytic converter, oxygen sensor, and other components of the emissions systems are working properly can help prevent environmental harm and maintain fuel efficiency.

By staying on top of these maintenance tasks, you can keep your engine in top condition and minimize the risk of the check engine light coming on unexpectedly.

Diagnostic Tools And Services

When the check engine light illuminates, it’s essential to get it checked out by a professional. At Hogan Tire & Auto, we use advanced diagnostic tools and scan tools to identify the source of the issue. Our certified technicians are trained to read the trouble codes generated by your car’s diagnostic system and provide an accurate assessment of the problem.

If your check engine light is flashing, this typically indicates a more serious issue, such as engine misfires, that requires immediate attention. Continuing to drive with a flashing warning light could lead to more severe engine damage and more costly repairs.

The Importance Of Addressing Engine Issues

Ignoring a check engine light or waiting too long to address an issue can lead to more significant problems, such as:

Engine misfires: If left unchecked, a misfire can damage the spark plugs, catalytic converter, or other engine components.
Fuel inefficiency: A failing mass airflow sensor or oxygen sensor can result in poor fuel economy, costing you more money at the pump.
Increased emissions: A malfunctioning emissions system can increase the amount of harmful gases your vehicle produces, which is bad for the environment and may cause your car to fail emissions testing.
