Engine Diagnostics in Lewisville, TX

When your check engine light goes off, it’s your car talking to you. At Eagle Transmission, we leverage the latest technology to diagnose your transmission problems as quickly and accurately as possible in order to get you back on the road sooner — without a costly repair.


Why Engine Diagnostics Matter

Today’s trucks and cars need computers and sensors to run correctly. And whenever things go wrong, your car tucks an error code under its cheek that indicates what it was. All of those codes are read by our high-tech scan tools and assist us in narrowing down the cause with guidance from our certified technicians.


Common Issues We Diagnose

Our engine diagnostics can uncover:

  • Bad oxygen or mass airflow sensor
  • I could go on to list more obvious points, but I hope you get what I'm getting at.
  • Fuel injector or fuel pump issues
  • Overheating or cooling system issues
  • Electrical system malfunctions
  • Emission system problems
