As your reliable local auto shop, we aim to demystify the diagnostic process, empower you with knowledge, and offer practical solutions tailored to your automotive needs.

What is the Check Engine Light?
The check engine light is part of your vehicle’s onboard diagnostics system. This warning light can alert you to a variety of issues, ranging from minor to severe, with your engine or emissions system. When the CEL lights up, your car's computer has detected a problem that needs attention. While it might be tempting to ignore the light if your car seems to drive fine, it's crucial to address the issue promptly to avoid potential damage and costly repairs later.
Common Causes of the CEL
There are several reasons the check engine light may illuminate, each varying in severity. Here are common causes:
Faulty Oxygen Sensor
This sensor measures the amount of unburned oxygen in your car’s exhaust system. A faulty sensor can lead to poor fuel economy and increased emissions. If not addressed, it might damage spark plugs and the catalytic converter.
Loose or Damaged Gas Cap
Sometimes, a CEL can appear simply because your gas cap is loose, cracked, or missing. The gas cap maintains pressure in your gas tank and prevents gasoline fumes from escaping, which helps maintain fuel efficiency.
Worn Spark Plugs
Essential for igniting the fuel-air mixture in the engine, worn spark plugs can lead to poor engine performance and reduced fuel efficiency. Replacing spark plugs is a cost-effective solution that can prevent further issues.
Faulty Catalytic Converter
A catalytic converter reduces exhaust gases by converting carbon monoxide and other harmful pollutants into less harmful emissions. A malfunctioning catalytic converter can result in poor vehicle performance and increased emissions.
