The check engine light is one of the most important warning indicators on your dashboard. When it illuminates, it’s signaling that something isn’t right under the hood. While some causes are minor, others can lead to significant engine damage if ignored. Understanding the common reasons behind a check engine light can help you address the issue promptly. At European Fine Car Repairs, we provide expert European check engine light diagnostics and repair in the greater Boca Raton, FL area. Here’s a look at five common check engine light triggers.

Malfunctioning Catalytic Converter

The catalytic converter plays a vital role in reducing harmful emissions by converting toxic gases into less harmful ones. When it fails, your vehicle’s performance can suffer, and emissions may increase significantly.

Bad Oxygen Sensor

Oxygen sensors measure the level of unburned oxygen in your car’s exhaust system and help regulate fuel-efficiency. A malfunctioning oxygen sensor can cause poor fuel-economy and increased emissions. Ignoring this issue may eventually cause problems with your catalytic converter.

Loose/Damaged Gas Cap

A loose, cracked, or missing gas cap might seem minor, but it can trigger the check engine light. 

With this issue, fuel might evaporate before your engine gets the chance to run on it. 

Failing Mass Airflow Sensor

The mass airflow sensor monitors the amount of air entering the engine and plays a central role in ensuring the proper fuel-to-air ratio for combustion. A failing sensor can result in poor engine performance, rough idling, and decreased fuel-efficiency.

Worn Spark Plugs or Ignition Coils

Spark plugs and ignition coils are responsible for igniting the air-fuel mixture in your engine. When they wear out or fail, misfires can occur, causing the check engine light to activate. This issue can also lead to reduced engine power and efficiency.
