Engine Diagnostics in Lewisville, TX

When your check engine light comes on, it’s your car’s way of saying something isn’t right. At Eagle Transmission & Auto Repair in Lewisville, we use advanced diagnostic tools to quickly identify the problem and recommend the right fix — before it becomes a costly repair.



Why Engine Diagnostics Matter

Modern vehicles rely on computers and sensors to run properly. When something goes wrong, your car stores an error code that points to the issue. Our state-of-the-art scan tools read those codes and help our certified technicians find the exact cause.


Common Issues We Diagnose

Our engine diagnostics can uncover:

  • Faulty oxygen or mass airflow sensors
  • Ignition coil and spark plug failures
  • Fuel injector or fuel pump problems
  • Overheating or cooling system issues
  • Electrical system malfunctions
  • Emission system problems

  • Check Engine Light On – Steady or flashing
  • Rough Idling or Misfires – Car shakes or stalls at stoplights
  • Poor Fuel Economy – You’re filling up more often
