Common Causes Of Check Engine Light

When the check engine light on your 2015 Nissan Altima illuminates, it can be a worrisome experience. However, understanding the common causes of this issue can help you identify the potential problem and take the necessary steps to resolve it.

Loose Gas Cap

A loose gas cap is one of the most common triggers for the check engine light. The fuel system in your Nissan Altima relies on a properly sealed gas cap to maintain optimal pressure. If the gas cap is loose, damaged, or missing, it can lead to an increase in fuel evaporative emissions, triggering the check engine light.

Failing Catalytic Converter

The catalytic converter plays a crucial role in reducing the emission of harmful gases from your vehicle’s exhaust. Over time, it can degrade due to excessive heat, engine misfires, or contaminated fuel. A failing catalytic converter can cause the check engine light to illuminate, indicating a potential issue that requires attention to ensure proper emissions control.

Fouled Spark Plugs

The spark plugs in your Nissan Altima are responsible for igniting the air-fuel mixture in the engine cylinders. If the spark plugs become fouled with deposits or wear out, it can lead to inefficient combustion and misfires, triggering the check engine light. Regular maintenance and timely replacement of spark plugs are essential to prevent this common cause of the check engine light.

Being aware of these common causes can empower you to address check engine light issues promptly, ensuring the continued reliability and performance of your 2015 Nissan Altima.
