Check Engine Light in Waltham, MA

Check Engine Light

Your vehicle’s dashboard is equipped with a range of warning lights, but none can be as unsettling as the dreaded “Check Engine” light. When that little amber indicator illuminates, it’s only natural to wonder what’s gone wrong with your vehicle and whether it’s safe to keep driving.

At Hogan Tire & Auto in Waltham, we understand the anxiety that can come with the sudden appearance of the check engine light, and we’re here to help.

What Does It Mean When My Check Engine Light Comes On?

The check engine light, also known as the Malfunction Indicator Lamp (MIL), serves as an early warning system for your vehicle’s internal health. When it lights up, it’s signalling that your vehicle’s onboard diagnostic systems have detected a potential problem or irregularity.

This can range from minor issues like a loose gas cap to more complex concerns such as problems with the fuel injector, ignition coil, emissions system, oil pressure, catalytic converter, oxygen sensor, mass airflow sensor, or engine misfires.

When your Check Engine light comes on, it typically means that your vehicle’s Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected a trouble code. These trouble codes provide specific information about the issue, making it easier for a technician to diagnose and fix the problem. However, it’s essential to address the issue promptly to prevent further damage to your vehicle and ensure it operates efficiently.

Can I Continue Driving If My Check Engine Light Is On?

One of the most common questions we hear is whether it’s safe to continue driving when the check engine light is on. The answer depends on the situation. If the light turns on and your vehicle’s performance remains normal, it’s generally safe to continue driving to your destination. However, it’s important to schedule a check engine light service at your earliest convenience to identify and fix the underlying issue.

On the other hand, if your vehicle experiences a noticeable decrease in performance, starts running roughly, or exhibits unusual noises, it’s advisable to pull over safely and turn off the engine. Continuing to drive in such conditions could cause further damage to your vehicle, leading to more extensive and costly repairs.

In some cases, a flashing check engine light indicates a severe problem that requires immediate attention. If you see your check engine light flashing, it’s best to pull over and turn off your engine right away. Continuing to drive with a flashing check engine light can result in severe engine damage, so it’s essential to seek assistance promptly.

What Are the Common Reasons for the Check Engine Light to Illuminate?

The check engine light can illuminate for a wide range of reasons. Here are some of the most common issues that can trigger the check engine light:

Loose Gas Cap: One of the simplest and most common reasons for the check engine light to turn on is a loose or improperly sealed gas cap. This can cause a minor leak in the fuel system and trigger the light.

Fuel Injector Problems: Issues with the fuel injectors, which control the delivery of fuel into the engine, can lead to an imbalance in the air-fuel mixture and trigger the check engine light.

Ignition Coil Failure: A failing ignition coil can disrupt the spark plugs’ operation, leading to engine misfires and the illumination of the check engine light.

Emissions System Problems: The emissions system, including components like the catalytic converter and oxygen sensor, plays a crucial role in reducing harmful emissions. Malfunctions in this system can result in a check engine light activation.

Oil Pressure Concerns: Low oil pressure can lead to engine damage, and the check engine light can turn on to warn you about this critical issue.

Mass Airflow Sensor Issues: The mass airflow sensor measures the amount of air entering the engine, and problems with this sensor can affect engine performance and trigger the light.
