What’s Causing My Check Engine Light?
Check Engine Lights can mean anything from a loose gas cap to a major repair to your engine. You won’t know what’s wrong until you bring in your car to a professional at Certified Automotive Repair. Here are some of the most common explanations for a Check Engine Light:
- Replace your oxygen sensor: If your oxygen sensor isn’t working correctly, it could reduce your fuel economy.
- Replace or tighten your gas cap: Sometimes, a missing or loosened gas cap is all you need to turn off your Check Engine Light.
- Replace your catalytic converter: You need a functioning catalytic converter to pass emissions tests.
- Replace your Mass Airflow Sensor: Could cause damage to your spark plugs
- Replace your spark plugs or wiring: Reduced power or fuel economy, damage to ignition coils
