Why Is My Check Engine Light On

Our vehicles require regular maintenance to continue performing at their best. They come equipped with a wide range of warning signs that there may be an undetected issue. One of these warning signs is the check engine light (CEL). We all know what it looks like, but what exactly does it mean?

Determining the Severity of Situation 

The idea of suddenly needing to check your engine can be stressful. When the light remains on, and as long as the vehicle appears to be operating fine, it is okay to keep driving. You should still get your vehicle serviced as soon as possible to pinpoint the cause of the problem. If the light is flashing, this means you need to pull over immediately. A flashing check engine light indicates that there is a serious issue that could cause major damage.

Common Causes of CEL

  • The gas cap is loose, damaged, or missing. Your gas cap plays an important role in your vehicle’s system that recirculates gasoline vapors. If you forget to tighten your gas cap, your CEL will come on rather quickly. If not addressed, you can lose fuel through evaporation, and cause the overall recirculating system to not function properly.
  • Failed oxygen sensors. Your oxygen sensors measure the amount of unburned oxygen in your exhaust system. If left unfixed, you’ll burn more fuel than necessary and lose fuel economy.
  • Catalytic converter. Your converter is responsible for converting carbon monoxide to carbon dioxide. It rarely fails on its own and is often part of a larger problem. It can reduce your vehicle’s performance and fuel economy as well as fail an emissions test.

Have Your Vehicle Assessed  

When your check engine light comes on, it’s important to have your vehicle inspected. In many cases, it’s an easy fix. When left unattended, the problem could get worse, leading to more costly repairs. If your check engine light comes on, contact us to schedule an appointment.
