Check Engine Light Diagnostics in Friendswood, TX

Is your check engine light on? Don’t ignore it. At Eagle Automotive & Transmission in Friendswood, TX, we use advanced diagnostic tools to quickly find out what’s wrong with your vehicle. Whether it’s a simple sensor or a bigger issue, we’ll give you clear answers and honest repair options.


What Does the Check Engine Light Mean?

Your car’s computer monitors hundreds of components. When something goes wrong, the check engine light comes on. The cause can range from minor to serious, including:

  • Loose or faulty gas cap
  • Oxygen sensor failure
  • Mass airflow sensor issues
  • Spark plug or ignition coil problems
  • Fuel system or injector issues
  • Transmission or drivetrain trouble
  • Emission control system failures

Because the light doesn’t tell you exactly what’s wrong, a professional diagnostic is the only way to know for sure.
