Conducir con la luz del motor encendida: ¿imminent danger or just a warning?

The check engine light illuminated on a vehicle’s dashboard can cause great concern among drivers. This signal, symbolized by an orange icon representing an engine, can be interpreted in various ways. But is it really a direct danger or just a benign warning? Understanding its meaning and the implications of driving with this light on is essential to ensure road safety and the proper functioning of the vehicle.

When the check engine light comes on in a vehicle’s dashboard, it can create anxiety among drivers. This indicator can signify anything from a minor issue to a critical situation requiring immediate attention. In this article, we will explore how the check engine light works, common causes for its illumination, the implications of driving with the light on, and the actions to take when this occurs.

Understanding the function of the check engine light

What is the check engine light?

The check engine light is an essential component of the vehicle’s monitoring system. It activates when the on-board diagnostic system (OBD) detects an anomaly in the engine’s performance or in related components. However, the mere fact that the light comes on does not specify the problem, which is why a specialized scanner is required to identify the exact cause.

The importance of this signal

The check engine light can be an indicator of various mechanical problems, from something as simple as a poorly closed gas cap to failures in crucial engine components. It is essential to pay attention to this signal to avoid greater damage to the vehicle and ensure the safety of the driver and passengers.

Common causes of the check engine light activation

There are multiple reasons why the check engine light can turn on, and knowing the most common ones can facilitate diagnosis and repair.

Anomalies in the exhaust system

One of the most frequent reasons for the check engine light activation is related to the exhaust system. Issues such as a defective catalytic converter or a malfunctioning lambda sensor are the primary culprits that trigger this warning. It is important to address these issues immediately to minimize environmental impact and comply with emission regulations.

Mechanical difficulties of the engine

A malfunction in the engine itself, such as an ignition defect, overheating, or low oil levels, can cause the light to activate. This situation requires immediate attention to avoid further damage affecting the vehicle’s performance.

Meaning of the different manifestations of the check engine light

The check engine light can present itself in various ways, and each has a specific meaning.

Solid orange light

A solid orange light indicates a problem that is not critical, but should not be ignored. It is recommended to schedule an appointment with a mechanic for a detailed evaluation.

Flashing orange light

When the light starts to flash, it is a sign that a serious problem has been detected. In this case, it is crucial to stop the vehicle immediately and seek professional assistance.

Red light

A red signal indicates a critical situation. Generally, it is associated with overheating or severe failures that require stopping the vehicle and urgently contacting a specialized technician.

Risks of driving with the check engine light on

It is not advisable to continue driving with the check engine light on, as this can entail several risks.

Development of additional failures

Ignoring the check engine light activation can lead to additional problems. An unattended defect can spread and affect other components of the vehicle. For instance, a damaged catalytic converter can lead to issues in lambda sensors or increase fuel consumption.

Increased repair costs

The longer you wait to resolve a mechanical problem, the more expensive the repairs will be. Additionally, since 2017, a vehicle with the check engine light on will not pass technical inspection, which implies repairs before the mandatory review.

What to do when the check engine light turns on?

The response to the activation of the check engine light will depend on its behavior.

Solid or flashing light

If the light is solid, it is advisable to continue driving gently and take the vehicle to the mechanic as soon as possible. However, if the light is flashing, the car should be stopped immediately and a towing service should be called.

Consult a professional

Whatever the manifestation of the check engine light, it is necessary to consult a professional. A specialized technician has the necessary tools to read the error codes stored in the system and determine the cause of the problem.

When to consult a professional about the check engine light

The reaction to the check engine light should be swift, but it is essential to evaluate the urgency of the matter.

For a solid light, it is sufficient to schedule a visit to the mechanic in the coming days. However, if the light is flashing, it is considered an emergency, and help should be sought immediately.

In all cases

Never underestimate an illuminated check engine light. Although the vehicle may function normally, the light can be a signal of a problem that could worsen over time.

Therefore, driving with the check engine light on is not a trivial matter. Whether it is orange or red, solid or flashing, this signal indicates a malfunction that should not be ignored. It is essential to consult an expert as soon as this light appears, thus avoiding greater problems and ensuring the longevity of the vehicle.

Conclusion on the status of the illuminated check engine light

Driving with the check engine light on is a situation that many drivers face. It is essential to understand that this indicator is not just a warning, but also a signal that can indicate problems ranging from minor to severe within the vehicle. Ignoring this sign can lead to a series of complications, from extensive engine damage to costly repairs that could have been avoided with timely intervention.

Depending on the nature of the alert, knowledge is key. A check engine light that remains solid may seem less urgent compared to one that flashes, which typically indicates a serious issue requiring immediate attention. Understanding the difference between these two types of alerts can make a significant difference in how the issue is addressed and in the final condition of the vehicle.

The causes that activate the check engine light are diverse and can include anything from system failures related to emissions to more serious problems directly associated with the engine. Therefore, it is advisable to conduct a professional assessment as soon as possible to diagnose the situation accurately. This not only contributes to the health of the car but also ensures the safety of the driver and passengers.

Finally, remember that prevention is the best strategy. Keeping the vehicle in optimal condition through regular maintenance, periodic inspections, and conscious driving can prevent the check engine light from turning on. Paying attention to every signal from the car is essential on the path to a safer and more enjoyable driving experience.
