Check Engine Light in Lewisville, TX

When the check engine light turns on, it’s easy to worry — but let’s not jump to conclusions! At Eagle Transmission & Auto Repair of Lewisville, we offer quick and precise check engine light diagnostics that will help locate the problem and get you back on the road safely.

What the Engine Check Light Means

Your check engine light is linked to your car’s computer system. The light comes on when a sensor discovers something amiss in the engine, transmission or emission control system. This might be something as simple as a loose gas cap — or as serious as an engine misfire.

Some of the problems that our diagnostic tools can detect include:

Loose or damaged gas cap
Oxygen sensor failure
Broken spark plugs or bad ignition coil.
Mass airflow sensor problems
Fuel system issues
Transmission-related trouble codes
Emission system malfunctions
