By keeping up with these tasks on a regular basis, you can reduce the chances of your Check Engine Light illuminating due to an underlying issue.

Possible Causes of the Check Engine Light Illuminating

There are several possible causes for a CEL illumination. These include problems with engine performance such as misfires or fuel delivery issues, problems with emissions such as faulty oxygen sensors or catalytic converters, and fluid leaks that can cause an increase in exhaust gases. Other issues such as worn or faulty spark plugs or air filters can also cause a CEL illumination.

Common Diagnostic Problem Areas

When diagnosing any problem related to a CEL illumination, it is important to look at both engine performance and emissions systems for potential causes. Common areas where problems can be found include engine misfires or other fuel delivery issues, faulty oxygen sensors or catalytic converters, fluid leaks that increase exhaust gas levels, worn or faulty spark plugs or air filters, and other similar issues that can cause a CEL illumination.

Malfunction Indicator Lamp (MIL) Symptoms

The MIL (or Malfunction Indicator Lamp) is an indicator on some vehicles which warns drivers when there is an issue with one of their vehicle’s systems.
