Why You Should Never Ignore the Check Engine Light

The thought of going on a road trip is exciting and filled with a lot of mixed experiences, however, it is important to learn about certain safety precautions like checking the engine light before you embark on one. This article will tell you about the importance of looking into an indicator such as the check engine light, what it is, how it works and why it matters in the long run.

Understanding the Check Engine Light

The check engine light indicator indicates the health of your vehicle’s engine. It alerts you to possible problems in the functioning of your vehicle’s engine. The engine check light is a universal indicator present in the dashboard. This indicator is connected to an advanced computer system that monitors various sensors and components in most modern vehicles. This light comes on when the sensor detects any issues alerting you to potential problems in the engine's functioning.

Common Reasons for Illumination

The car check engine light can turn on for various reasons:

Loose or Faulty Gas Cap

A loose or missing gas cap can affect the fuel system's pressure and, as a result, impact fuel economy.

Oxygen Sensor Malfunction

The oxygen sensor measures the amount of unburnt oxygen in the exhaust. A faulty sensor can lead to decreased fuel efficiency and increased emissions.

Catalytic Converter Issues

A catalytic converter ensures that your vehicle emissions are less fatal to the atmosphere. If this component of the engine malfunctions, it sets off the engine check light. It is important to ensure that the catalytic converter works well in order to keep your emissions in check. If it malfunctions and is left unattended, it may lead to emission issues, thus causing it difficult for you to get a PUC certificate which is a mandatory document to be owned by all vehicle owners in India.  

Faulty Spark Plugs or Wires

Spark plugs and wires are important for engine ignition and overall performance. Faulty spark plugs can lead to fatal accidents or cause terrible fires. It can also reduce fuel efficiency. Hence, if your Check Engine light blinks, get your car checked immediately.

Mass Airflow Sensor Problems

The Mass Airflow (MAF) sensor is crucial to controlling the amount of air entering the engine. This in turn affects the air-fuel ratio. If your vehicle’s MAF is malfunctioning, you must get it checked as it affects your engine’s performance and leads to a decreased fuel efficiency.

The Dangers of Ignoring the Check Engine Light

The above paragraphs have highlighted some of the most common but crucial reasons behind why your Check Engine light could blink. Here are a few major reasons why ignoring this indicator may prove to be unsafe in the long run.

Escalation of Minor Issues

Small problems can turn into expensive repairs if ignored. Addressing issues early can prevent breakdowns and costly repairs.

Decreased Fuel Efficiency

Some issues, like faulty oxygen sensors or engine misfires, can affect fuel efficiency, increasing fuel costs.

Environmental Concerns

Ignoring vehicle problems contributes to pollution and increased emissions.

Safety Risks

Some check engine light issues, such as engine misfires or problems with the braking system, can impact vehicle safety. Ignoring the light can increase the chances of vehicle breakdowns or accidents.

Immediate Steps to Take When the Check Engine Light Comes On

When the check engine light comes on, take these steps:

Check the Gas Cap

Ensure the gas cap is tightened properly to avoid false alarms.

Observe Vehicle Performance

Pay attention to any changes in vehicle performance, such as reduced power, strange noises, or vibrations.

Seek Professional Diagnostic Services

Consult a certified mechanic or use an OBD-II scanner to diagnose the problem accurately.

Preventive Measures for Drivers

To prevent check engine light issues, follow: 

Regular Vehicle Maintenance

Follow the manufacturer’s recommended service schedule to keep your vehicle in good condition.

Buy Engine Protection Cover With Your Insurance

In India, all vehicle owners must own insurance. Comprehensive car insurance provides some of the basic financial covers required to repair small engine damages. However, if you are looking for a cover that particularly helps with engine repair, then consider buying an engine protection cover, alongwith your insurance policy. 

Using Quality Fuel

Using high-quality fuel can prevent damage to sensors and other components.

Awareness of Local Driving Conditions

Be mindful of how road conditions affect your vehicle's health.
