While it might be tempting to ignore your check engine light, it's an important indication that something in your vehicle needs attention. Understanding the common reasons behind the check engine light can help you address issues before they become more serious and costly. At The Organic Mechanic, we provide expert check engine light diagnostics and repair in the greater Asheville area. Here’s a look at five common check engine light triggers.

Faulty Oxygen Sensor

The oxygen sensor monitors the amount of unburned oxygen in your vehicle’s exhaust system. A faulty oxygen sensor is a common reason for the check engine light to come on, and ignoring it can result in poor performance and issues with the catalytic converter.

Malfunctioning Catalytic Converter

The catalytic converter is an essential part of your vehicle’s exhaust system. It helps reduce harmful emissions by converting pollutants into less harmful substances. When the catalytic converter isn’t functioning properly, it can trigger the check engine light. 

Failing Mass Airflow Sensor

The mass airflow sensor measures the amount of air entering the engine and determines how much fuel is needed to achieve optimal combustion. If the sensor is faulty or dirty, it can lead to incorrect air-to-fuel ratios, resulting in poor fuel economy, rough idling, and even engine stalling. 

Loose/Faulty Gas Cap

It might surprise you to learn that something as simple as a loose or damaged gas cap can trigger the check engine light. The gas cap seals the fuel system. If it’s faulty, fuel may evaporate before it is directed to the engine.

Worn-Out Spark Plugs or Ignition Coils

Spark plugs and ignition coils are responsible for igniting the air-fuel mixture in your engine’s cylinders. When spark plugs wear out or ignition coils fail, it can lead to engine misfires, reduced power, and poor fuel-efficiency. Replacing spark plugs and ignition coils is a relatively straightforward fix.
