Lewisville Drivers – Is Your Check Engine Light On? Find Out Why Today!

Say you’re making the trip from Lewisville into Dallas or Fort Worth and the dreaded check engine light in your instrument cluster lights up. Your stomach may turn at the thought of a major auto repair or a vehicle breakdown, but don’t panic—the check engine light can signify plenty of minor issues, and unless the light is flashing, your car is unlikely to breakdown any time soon. But that’s not to say you don’t need to be concerned. The issue giving your engine trouble will likely become worse without prompt attention and could lead to additional system failures. If you’re in the Lewisville area, bring your vehicle to Auto Science for a check engine light diagnostic, and we’ll get to the root of the problem.

Potential Reasons Your Check Engine Light May Be On

All vehicles made after 1996 come standard with an on-board computer diagnostic (OBD) system that serves many functions. First, it monitors the engine’s exhaust emissions to help ensure it’s running cleanly and efficiently. OBD systems also use sensors to monitor a variety of engine components for proper operation. When the OBD system detects a problem, it notifies the engine control unit (ECU)—the computer in charge of your engine’s air/fuel mixture, timing, emissions, and other functions. Depending on the type and severity of the problem, the ECU might adjust the engine to compensate or trigger the check engine light to let you know there’s an issue. Some of the most common reasons your check engine light may be on include:

Reason	What Could Happen if You Don’t Get Service
Oxygen sensor replacement warning	Decreased efficiency and damage to the spark plugs and/or catalytic converter
Loose, damaged, or no gas cap	Decreased efficiency
Airflow sensor replacement warning	Decreased performance and efficiency
Catalytic converter replacement warning	Damage to parts such as the catalytic converter, oxygen sensors, spark plugs, etc. and decreased performance and efficiency
Spark plug replacement warning	Decreased performance and efficiency and damage to parts such as spark plugs, catalytic converter, oxygen sensors, ignition coils, etc.
