That yellow light on your dashboard can be a source of anxiety. But don't worry, WrenchTree Automotive in Lynchburg is here to help! We specialize in engine diagnostics and resolving check engine light issues, ensuring your vehicle runs smoothly and efficiently.

What Does the Check Engine Light Mean?

The check engine light is part of your vehicle's onboard diagnostic system (OBD-II). When it illuminates, or when you see the engine light on, it signals that the computer has detected a potential problem within your engine or emission control system. 

Common Causes of a Check Engine Light

While a check engine light can indicate a wide range of issues, here are some of the most common culprits:

• Loose Gas Cap: A simple but frequent cause!
• Oxygen Sensor Failure: Affects fuel efficiency and emissions. 
• Worn Spark Plugs: Can cause misfires and poor performance. 
• Catalytic Converter Problems:  Reduces emissions; failure can impact performance. 
• Mass Airflow Sensor (MAF) Issues:  Measures air intake; problems can affect engine operation. 
• EVAP System Leak:  Often caused by a loose or damaged gas cap or a leak in the fuel vapor recovery system. 
• Transmission Problems: Can affect shifting and overall performance. 
• Fuel Injector Malfunction:  Can lead to poor fuel delivery and engine performance. 
• Battery and Charging System Issues:  Can disrupt the vehicle's electrical system.
