Understanding Your Check Engine Light

The check engine light (sometimes called the "Malfunction Indicator Lamp" or MIL) can signal a wide range of issues, from a simple loose gas cap to a complex engine problem. It's crucial not to dismiss it, as even minor issues can become major if left unaddressed. Our team uses advanced diagnostic tools to "read" the codes stored in your vehicle's computer, which helps pinpoint the exact nature of the problem. 
If you are having a check engine light warning  appearing on your dashboard, make sure to get in touch as soon as possible with an auto repair near you, like GLP Automotive.

Common Reasons Your Check Engine Light Comes On

While only a professional diagnosis can confirm the exact cause, here are some of the most common reasons the check engine light illuminates:

Loose or Faulty Gas Cap

This is often the simplest fix but can trigger the light due to an evaporative emissions system leak.

Failing Oxygen Sensor (O2 Sensor)

A bad O2 sensor can reduce fuel economy and increase emissions, potentially damaging catalytic converters over time.

Bad Catalytic Converter

This is a more serious and costly repair, often caused by prolonged issues with other components. It impacts emissions and performance.

Faulty Spark Plugs or Ignition Coils

Misfires can trigger the light, leading to poor engine performance and reduced fuel efficiency.

Mass Airflow Sensor (MAF) Failure

An inaccurate MAF sensor can affect fuel delivery and engine performance.

Vacuum Leak

Leaks in the vacuum system can cause rough idling and other performance issues.

Evaporative Emission (EVAP) System Issues

Problems with this system (which prevents fuel vapors from escaping into the air) are a common cause.

Bad Battery or Charging System Issues

While often indicated by a battery light, sometimes electrical issues can trigger the check engine light.
